将数据存入csv文件时报错,然后各种查,就是解决不了,rows类型为list

部分源码:
with open(city+'.csv','a') as f:

fieldnames = ['name','area','address','total_price','unit_price','house_size','house_type']
writer = csv.DictWriter(f, fieldnames=fieldnames)
writer.writeheader()
46 rows = [name,area,address,total_price,unit_price,house_size,house_type,number]
47 print(type(rows))
48 writer.writerow(rows)

Adding up Triangles 如何实现三角形算法
Problem Description Take a look at the triangle on the left of the figure below. It is made of 9 (unit) triangles arranged in three rows (N = 3 ). Needless to say, a unit triangle is a triangle with N = 1 . If you study the figure for few seconds, you'll realize that you can find 13 different triangles (which we'll call sub-triangles.) Of these 13 sub-triangles we have: Nine unit triangle; three with N = 2 , and one with N = 3 . The following table lists the number of sub-triangles in arrangements with N < 5 . Let's define the value of a unit triangle to be the integer value written in that triangle. In general, the value of a triangle is the sum of values in all its unit triangles. The triangle on the right is the same as the other one but with the sub-triangle having the largest value being highlighted. Write a program to determine the sub-triangle with the largest value. Input Your program will be tested on one or more test cases. Each test case is specified in a single line made of integers (separated by spaces.) The first integer is the number of rows in the test case, and the remaining integers are the values of the unit triangles specified in a top-down, left-to-right order. (the first test case in the example below is the same as the one in the figure.) The last line of the input file contains the number 0 (which is not part of the test cases.) The maximum number of rows is 400. The absolute value of a unit triangle is less than 1000. Output For each test case, print the result using the following format: k . V where k is the test case number (starting at 1,) is a single space, and V is the maximum value of a sub-triangle in that test case. Sample Input 3 6 -24 0 12 -10 12 40 -4 6 4 1 1 -1 1 1 -1 1 -1 1 1 -1 1 -1 1 -1 1 0 Sample Output 1. 54 2. 4
Hex Tile Equations 等式问题
Problem Description An amusing puzzle consists of a collection of hexagonal tiles packed together with each tile showing a digit or '=' or an arithmetic operation '+', '-', '*', or '/'. Consider continuous paths going through each tile exactly once, with each successive tile being an immediate neighbor of the previous tile. The object is to choose such a path so the sequence of characters on the tiles makes an acceptable equation, according to the restrictions listed below. A sequence is illustrated in each figure above. In Figure 1, if you follow the gray path from the top, the character sequence is"6/3=9-7". Similarly, in Figure 2, start from the bottom left 3 to get "3*21+10=73". There are a lot of potential paths through a moderate sized hex tile pattern. A puzzle player may get frustrated and want to see the answer. Your task is to automate the solution. The arrangement of hex tiles and choices of characters in each puzzle satisfy these rules: The hex pattern has an odd number of rows greater than 2. The odd numbered rows will all contain the same number of tiles. Even numbered rows will have one more hex tile than the odd numbered rows and these longer even numbered rows will stick out both to the left and the right of the odd numbered rows. 1.There is exactly one 2. '=' in the hex pattern. 3. There are no more than two '*' characters in the hex pattern. 4. There will be fewer than 14 total tiles in the hex pattern. 5.With the restrictions on allowed character sequences described below, there will be a unique acceptable solution in the hex pattern. To have an acceptable solution from the characters in some path, the expressions on each side of the equal sign must be in acceptable form and evaluate to the same numeric value. The following rules define acceptable form of the expressions on each side of the equal sign and the method of expression evaluation: 6.The operators '+', '-', '*', and '/' are only considered as binary operators, so no character sequences where '+' or '-' would be a unary operator are acceptable. For example "-2*3=-6" and "1 =5+-4" are not acceptable. 7.The usual precedence of operations is not used. Instead all operations have equal precedence and operations are carried out from left to right. For example "44-4/2=2+3*4" is acceptable and "14=2+3*4" is not acceptable. 8.If a division operation is included, the equation can only be acceptable if the division operation works out to an exact integer result. For example "10/5=12/6" and "7+3/5=3*4/6" are acceptable. "5/2*4=10" is not acceptable because the sides would only be equal with exact mathematical calculation including an intermediate fractional result. "5/2*4=8" is not acceptable because the sides of the equation would only be equal if division were done with truncation. 9.At most two digits together are acceptable. For example, " 9. 123+1 = 124" is not acceptable. 10.A character sequences with a '0' directly followed by another digit is not acceptable. For example,"3*05=15" is not acceptable. With the assumptions above, an acceptable expression will never involve an intermediate or final arithmetic result with magnitude over three million. Input The input will consist of one to fifteen data sets, followed by a line containing only 0. The first line of a dataset contains blank separated integers r c, where r is the number of rows in the hex pattern and c is the number of entries in the odd numbered rows. The next r lines contain the characters on the hex tiles, one row per line. All hex tile characters for a row are blank separated. The lines for odd numbered rows also start with a blank, to better simulate the way the hexagons fit together. Properties 1-5 apply. Output There is one line of output for each data set. It is the unique acceptable equation according to rules 6-10 above. The line includes no spaces. Sample Input 5 1 6 / 3 = 9 - 7 3 3 1 + 1 * 2 0 = 3 3 7 5 2 9 - * 2 = 3 4 + 8 3 4 / 0 Sample Output 6/3=9-7 3*21+10=73 8/4+3*9-2=43
Robot Navigation 机器人导航问题
Problem Description A robot has been sent to explore a remote planet. To specify a path the robot should take, a program is sent each day. The program consists of a sequence of the following commands: FORWARD X: move forward by X units. TURN LEFT: turn left (in place) by 90 degrees. TURN RIGHT: turn right (in place) by 90 degrees. The robot also has sensor units which allow it to obtain a map of its surrounding area. The map is represented as a grid. Some grid points contain hazards (e.g. craters) and the program must avoid these points or risk losing the robot. Naturally, if the initial location of the robot, the direction it is facing, and its destination position are known, it is best to send the shortest program (one consisting of the fewest commands) to move the robot to its destination (we do not care which direction it faces at the destination). You are more interested in knowing the number of different shortest programs that can move the robot to its destination. However, the number of shortest programs can be very large, so you are satisfied to compute the number as a remainder modulo 1,000,000. Input There will be several test cases in the input. Each test case will begin with a line with two integers N M Where N is the number of rows in the grid, and M is the number of columns in the grid (2 ≤ N, M ≤ 100). The next N lines of input will have M characters each. The characters will be one of the following: ‘.’ Indicating a navigable grid point. ‘*’ Indicating a crater (i.e. a non-navigable grid point). ‘X’ Indicating the target grid point. There will be exactly one ‘X’. ‘N’, ‘E’, ‘S’, or ‘W’ Indicating the starting point and initial heading of the robot. There will be exactly one of these. Note that the directions mirror compass directions on a map: N is North (toward the top of the grid), E is East (toward the right of the grid), S is South (toward the bottom of the grid) and W is West (toward the left of the grid). There will be no spaces and no other characters in the description of the map. The input will end with a line with two 0s. Output For each test case, output two integers on a single line, with a single space between them. The first is the length of a shortest possible program to navigate the robot from its starting point to the target, and the second is the number of different programs of that length which will get the robot to the target (modulo 1,000,000). If there is no path from the robot to the target, output two zeros separated by a single space. Output no extra spaces, and do not separate answers with blank lines. Sample Input 5 6 *....X .....* .....* .....* N....* 6 5 ....X .**** .**** .**** .**** N**** 3 3 .E. *** .X. 0 0 Sample Output 6 4 3 1 0 0
Distinct Sub-matrix 矩阵的问题
Problem Description In this problem, let us consider an N*M matrix of capital letters. By selecting consecutive columns and rows, we can define the sub-matrix as the elements on chosen columns and rows. Two sub-matrices should be regarded the same if and only if they have the same dimensions and characters (which, of course, are capital letters) on corresponding position. It is your task to find the number of distinct sub-matrices of a given letter matrix. Input The input contains a lot of test cases. The first line of input contains exactly one integer, indicating the number of test cases. For each of the test case, the first line contains two integers N and M, denoting the number of rows and columns of the given matrix. (1 <= N, M <= 128) The next N lines contain only capital letters, indicating the given matrix. Output For each test case, output a single integer denoting the number of distinct sub-matrices. Sample Input 2 2 2 AB BA 3 3 ABA BAA AAA Sample Output Case #1: 7 Case #2: 22

Hiking Trip 旅行的问题
Problem Description Hiking in the mountains is seldom an easy task for most people, as it is extremely easy to get lost during the trip. Recently Green has decided to go on a hiking trip. Unfortunately, half way through the trip, he gets extremely tired and so needs to find the path that will bring him to the destination with the least amount of time. Can you help him? You've obtained the area Green's in as an R * C map. Each grid in the map can be one of the four types: tree, sand, path, and stone. All grids not containing stone are passable, and each time, when Green enters a grid of type X (where X can be tree, sand or path), he will spend time T(X). Furthermore, each time Green can only move up, down, left, or right, provided that the adjacent grid in that direction exists. Given Green's current position and his destination, please determine the best path for him. Input There are multiple test cases in the input file. Each test case starts with two integers R, C (2 <= R <= 20, 2 <= C <= 20), the number of rows / columns describing the area. The next line contains three integers, VP, VS, VT (1 <= VP <= 100, 1 <= VS <= 100, 1 <= VT <= 100), denoting the amount of time it requires to walk through the three types of area (path, sand, or tree). The following R lines describe the area. Each of the R lines contains exactly C characters, each character being one of the following: ‘T’, ‘.’, ‘#’, ‘@’, corresponding to grids of type tree, sand, path and stone. The final line contains four integers, SR, SC, TR, TC, (0 <= SR < R, 0 <= SC < C, 0 <= TR < R, 0 <= TC < C), representing your current position and your destination. It is guaranteed that Green's current position is reachable – that is to say, it won't be a '@' square. There is a blank line after each test case. Input ends with End-of-File. Output For each test case, output one integer on one separate line, representing the minimum amount of time needed to complete the trip. If there is no way for Green to reach the destination, output -1 instead. Sample Input 4 6 1 2 10 T...TT TTT### TT.@#T ..###@ 0 1 3 0 4 6 1 2 2 T...TT TTT### TT.@#T ..###@ 0 1 3 0 2 2 5 1 3 T@ @. 0 0 1 1 Sample Output Case 1: 14 Case 2: 8 Case 3: -1
No Left Turns 转弯的问题
Problem Description ALL HEADS: You're a Knight of the Round Table? ROBIN: I am. LEFT HEAD: In that case I shall have to kill you. MIDDLE HEAD: Shall I? RIGHT HEAD: Oh, I don't think so. MIDDLE HEAD: Well, what do I think? LEFT HEAD: I think kill him. RIGHT HEAD: Well let's be nice to him. MIDDLE HEAD: Oh shut up. As the story goes, the Knight scarpers off. Right Head has taken it upon himself to search the grounds for the knight so he, Left, and Middle can go extinguish him (and then have tea and biscuits.) Consider the following 8 by 12 maze, where shaded squares are walls that can’t be entered. The shortest path between the Right Head (denoted by the S, for start) and the knight (denoted by the F, for finish) is of length 3, as illustrated above. But! Right Head can’t turn left or make UTurns. He can only move forward and turn right. That means the shortest path that Right Head can find is significantly longer: at 29! Input The input file will consist of a single integer N (N > 0) specifying the number of mazes in the file. Following this, on a maze by maze basis will be the number of rows, r (3 < r <= 20), a space, then the number of columns, c (3 < c <= 20). After this will follow r lines of c characters, representing a map of the maze: XXXXXXXXXXXXXX X XXX X XFXXXXX X XXX XX XX X X S X XX XXXXXX X X X X X X X X X X X XXX XX X XXXXXXXXXXXXXX X’s mark those locations that are walls and can’t be occupied. S marks the start location, and F marks the Knight. Blanks are locations that can be freely traveled. Output The output is the length of the shortest path between the start and finish locations. Based on the above maze, your program would output the minimum no-left-turns path length of 29. Hint Additional Constraints/Information: Right Head is capable of moving from the start position in any of the four primary compass directions. After that, he’s constrained to either step forward or right. The start and end locations will never be the same. The maze is always surrounded by four walls. You can assume that a path between the start and final locations always exists. Sample Input 1 10 14 XXXXXXXXXXXXXX X XXX X XFXXXXX X XXX XX XX X X S X XX XXXXXX X X X X X X X X X X X XXX XX X XXXXXXXXXXXXXX Sample Output 29
Playfair Cipher 加密的问题
Problem Description The Playfair cipher is a manual symmetric encryption technique and was the first digraph substitution cipher. The scheme was invented in 1854 by Charles Wheatstone, but bears the name of Lord Playfair who promoted the use of the cipher. The Playfair cipher uses a 5 by 5 table containing each letter in the English alphabet exactly once (except 'Q' which is missing). The table constitutes the encryption key. To more easily remember the table, it is typically generated from a key phrase. First fill in the spaces in an empty table with the letters of the key phrase (dropping spaces and duplicate letters), then fill the remaining spaces with the rest of the letters of the alphabet in order. The key phrase is written in the top rows of the table, from left to right. For instance, if the key phrase is "playfair example", the encryption key becomes To encrypt a message, one would remove all spaces and then break the message into digraphs (groups of 2 letters) such that, for example, "Hello World" becomes "HE LL OW OR LD". Then map them out on the key table, and apply the rule below that matches the letter combination: If both letters are the same (or only one letter is left), add an 'X' after the first letter. Encrypt the new pair and continue (note that this changes all the remaining digraphs). If the letters appear on the same row of your table, replace them with the letters to their immediate right respectively (wrapping around to the left side of the row if a letter in the original pair was on the right side of the row). With the table above, the digraph 'CH' would be encrypted 'DB'. If the letters appear on the same column of your table, replace them with the letters immediately below respectively (wrapping around to the top side of the column if a letter in the original pair was on the bottom side of the column). With the table above, the digraph 'VA' would be encrypted 'AE'. If the letters are not on the same row or column, replace them with the letters on the same row respectively but at the other pair of corners of the rectangle defined by the original pair. The order is important { the first letter of the encrypted pair is the one that lies on the same row as the first letter of the plaintext pair. With the table above, the digraph 'KM' would be encrypted 'SR'. Write a program that reads a key phrase and a plaintext to encrypt, and outputs the encrypted text. The text to encrypt will not contain two 'x's following each other, or an 'x' as the last character, as this might cause the first rule above to repeat itself indefinitely. Input The input contains two lines. The first line contains the key phrase. The second line contains the text to encrypt. Each line will contain between 1 and 1000 characters, inclusive. Each character will be a lower case English letter, 'a' - 'z' (except 'q'), or a space character. Neither line will start or end with a space. Output The output should be a single line containing the encrypted text, in upper case. There should be no spaces in the output.

Equation of XOR 等式的问题
Problem Description Recently, Jimmy is learning about linear algebra from Blue Mary while having the course of Boolean algebra in class offered by Prof. Z. Since Jimmy has been thoroughly bored by the boring homework assigned by two teachers, evil Jimmy plans to set a hard question to baffle them as revenge for their heavy tasks. As a result, Jimmy comes up with an idea that merging the knowledge from both the two classes and constructs a complicate problem: the XOR equation system. Let’s consider the following equations: (a11 . x1) ^ (a12 . x2) ^ … ^ (a1m . xm) = 0 (a21 . x1) ^ (a22 . x2) ^ … ^ (a2m . xm) = 0 … (an1 . x1) ^ (an2 . x2) ^ … ^ (anm . xm) = 0 which satisfies the following conditions: 1. aij in {0,1} for 1 ≤ i ≤ n and 1 ≤ j ≤ m; 2. xi in Si where Si is a subset of {0,1,2,3}, 1 ≤ i ≤ m; 3. |Si| ≤ 3, 1 ≤ i ≤ m; 4. 1≤n ≤ 30, 1 ≤ m ≤ 22. In the system of equations, operation “ . “ denotes the multiplication operation while “ ^ ” is for bitwise XOR. Moreover, the bitwise XOR takes two bit patterns of equal length and performs the logical XOR operation on each pair of corresponding bits. The result in each position is 1 if the two bits are different, and 0 if they are the same. Rather than expecting a solution of a specified equation system, Jimmy would like to ask the teachers to calculate that how many distinct solutions can satisfy a given equation system. What a confusing puzzle! Help Jimmy’s teachers please! Input There are several test cases. The first line of input is a single positive integer T (<= 15) indicating the number of test cases, then T cases follow. For each test case, the first line contains two integers N and M giving the two dimensions of the equation system respectively where N is the number of rows and M for columns. Then N lines are following, each line contains m integers. Item at line i and column j represents aij. The next m lines are descriptions of Si that the leading integer K denotes the number of elements in Si and the following K integers represent elements. Output For each test case, output one line containing a single integer which represents the answer of this case. Sample Input 1 1 2 1 1 3 0 1 2 2 3 1 Sample Output 1
Palindrome Sub-Array 子数组的问题
Problem Description   A palindrome sequence is a sequence which is as same as its reversed order. For example, 1 2 3 2 1 is a palindrome sequence, but 1 2 3 2 2 is not. Given a 2-D array of N rows and M columns, your task is to find a maximum sub-array of P rows and P columns, of which each row and each column is a palindrome sequence. Input   The first line of input contains only one integer, T, the number of test cases. Following T blocks, each block describe one test case.   There is two integers N, M (1<=N, M<=300) separated by one white space in the first line of each block, representing the size of the 2-D array.   Then N lines follow, each line contains M integers separated by white spaces, representing the elements of the 2-D array. All the elements in the 2-D array will be larger than 0 and no more than 31415926. Output   For each test case, output P only, the size of the maximum sub-array that you need to find. Sample Input 1 5 10 1 2 3 3 2 4 5 6 7 8 1 2 3 3 2 4 5 6 7 8 1 2 3 3 2 4 5 6 7 8 1 2 3 3 2 4 5 6 7 8 1 2 3 9 10 4 5 6 7 8 Sample Output 4
Searching Treasure in Deep Sea 深度搜索
Problem Description A deep-sea salvage company found out that there was a sunken ship in some deep-sea area of the Pacific with a case of priceless treasure in it. The senior leaders concluded as followed: There may be some sea monsters, they may cause some distraction. The company had some most advanced intelligent underwater robots. They were equipped with enough weapons to kill the monster. After they research a map, they got information as follow (according to the Sample Input): S indicated the starting place. E indicated the place of the treasure case. D indicated the doors of the rooms in the ship. K indicated the keys which were needed while opening the doors. H indicated the stairs went up. L indicated the stairs went down. "#" indicated the walls which separated the rooms. Every lowercase in the map indicated a monster. The enclosed space formed by the doors and the walls was called a separated room. Entering a room needed a key K to open a door D. After that, the key could not be used any more, the door would be open for ever, and there would be no need to use the key. The total number of rooms in the ship was not exceeding 30, the total number of the monsters in the ship was not exceeding 26, and the number of the monsters in each room would not exceed 3. There was no monster in the rooms where S and E, H and L were in. The advanced intelligent underwater robot carried a machine gun whose cartridge clip capacity was 100 bullets and enough spare ammunition. It could re-load the bullets if given a chance. The surface of its body was equipped with 100 components. If all the components were destroyed while fighting with the monster, the robot could not function any more and would sink into the sea for ever. If only a part of the components was destroyed, the robot could recover if given a chance.The robot could attack the monsters in two ways; one is feign attack, and the other fierce attack. The feign attack would cause 1 reduction of the monsters' life value, and the fierce attack would cause a certain amount of deduction of the monsters' life value according to the degree of the fierce attack. The robot had 10 kinds of fierce attack tactics at most. Every attack tactics differed in bullet consumption and the certain reduction of the monsters' life value. For example, a certain kind of attack tactics would consume 30 bullets, and reduce 35 life value of the monster. The life of the monster was so limited that when the injuries accumulated to a certain amount it would be killed. Suppose its life value was 100, and every attack would reduce a certain amount of life value. When robot enters the treasure vessel, it searches the rooms one by one. As soon as it encounters the monsters, it will attack the monsters immediately. By consuming a certain amount of ammunition, a certain amount of the life value of the monsters is reduced. And then, the monsters attack the robot and destroy a certain number of robot's parts. Then they attack each other alternately like this. However, each time the robot launches attack firstly. If there are two or more monsters, the robot must kill the first one before another attack, and the monsters won't help each other in the battle. The choice of the order of attack is decisive when a number of monsters are in a room, because it closely relates with the final result of this battle. The robot itself and machine guns it takes possess the capacity of restoration. The robot will re-load 2 bullets when it launches an attack. In the same room, the robot will repair 10 damaged parts of the body surface and re-filled cartridges after it kills a monster. The robot can't leave the room until all monsters are eradicated. At the time he leaves the room, 100 damaged parts are repaired and 100 cartridges are refilled again. It should be noted that, under no circumstances will the robot's parts and bullets of cartridges be more than 100. Now intelligent underwater robot has been put into the sea, gradually approaching the location of the treasure vessel. Whether it can eradicate deep-sea monsters, and return the treasure box is the problem that you are supposed to resolve. Input There are several test cases. The first line of each case has 3 positive integers k, n and m (1 <= k <= 3, 1 <n, m <= 100), indicating that the deep-sea shipwreck is of k floors, each floor is a maze composed by n rows and m columns. (The Sample Input map is seen as below). That is, the maze is composed by characters of n lines, and each line has m characters. The following line has an integer p (0 <= p <= 10), indicating that there are p kinds of fierce attack tactics for the robot. Then there are a lines and each line has two positive integers, indicating the consumption of the number of bullets and reduction of the life value of the monsters as a result of injury by the robot's tactics. Then there is an integer q (0 <= q <= 26) taking up one line to indicate that there are q monsters in the treasure vessel. The following are q lines, and each line has one positive integer, indicating the number of damaged parts of the robot by those q monsters for one attack. Monsters are expressed in lowercase letters which are formed as a sequential increase from latter "a" to the letter "z". For example, when q = 10, then the names of the monsters are a, b, c, d, e, f, g, h, i, j, then the 10 lines of positive integers are the number of destroyed parts of robot as the result of the attack of those 10 monsters. Finally, there are k * n lines, every n lines indicates a floor of the ship, each line has m characters. The K floors are given from high to low. Input is terminated by the end of the file. Output For Each test case, if it can arrive "E" place, then output "Yes", or output "No". Each output takes up one line. Sample Input 1 5 10 0 0 ########## #S #K # E# #  #K #  # #  D  D  # ########## 3 5 10 1 1 10 3 1 2 3 ########## #  #aKKKK# #LKDcKKKK# ####bKKKK# ########## ########## #    DL K# #H ####### #  D  D E# ########## ########## #        # #  H     # #  S     # ########## Sample Output No Yes
Card Game 的代码的实现方法
Problem Description October 30, 2009. After a night's journey, finally we arrived at Wuhan University in the morning to participate the International Collegiate Programming Contest (ACM-ICPC). ...... Before went to sleep, my team mate Zhang and I played a popular card-game called "Builds up Train" to have a release. Although the game is a liite stupid, but it may have a lot of fun ... Assume there are 3 kinds of cards, and each of them has unlimited supply. If we take n cards out and arrange them in a row, we can get 3n differet rows. Now the problem is, how many different rows we can get using n cards and the number of cards of each kind is even? Input The first line of input is a single integer T (1 ≤ T ≤ 1000), representing the number of test cases. Then T test cases follows. Each test case is described by a single integer in a single line: n (1 ≤ n ≤ 2147483647); Output For each test case, output four integers in a line separated by spaces. The first integer is the number of different rows we can get using n cards when the number of cards of all kinds are even, the second integer is the number of different rows we can get using n cards when the number of cards of one kind is even and the number of cards of the other two are odd, the third integer is the number of different rows formed by n cards when the number of cards of two kinds are even and the number of cards of the other one is odd, the last number is the number of different rows formed by n cards when the number of cards of all three kinds are odd. Output the answer mod 40007. Sample Input 3 1 2 2147483647 Sample Output 0 0 3 0 3 6 0 0 0 0 442 13482

Play with Sequence 序列的问题
Problem Description   ivankevin loves sequences.   A sequence of n elements is called a SWITCH SEQUENCE iff:   Each element is a 2-switch, where a 2-switch is the replacement of a pair of edges xy & zw in a simple graph by the edges yz and wx, given that yz and wx did not appear in the graph originally.   Now give two simple graphs G and H with same vertex set V, ivankevin wants to know whether there is a switch sequence transforms G into H. Input   There are multiple test cases.   Each case contains 1 + 2n lines. The positive integer n(0<n<101) is given in the first line. The next 2n lines are the matrix which describe the two graphs G and H. The j elements in the i rows is either 0 or 1. If the node i and the node j has a edge in the graph. The elements will be 1. Otherwise is 0. It’s guaranteed that the matrix is symmetry and the i elements in the i row is always 0. See sample input for more details. Output   For each case, first output an integer L in a line, which should represent the length of the switch sequence you found.   If no switch sequence can transform G into H, then you should print L as -1 and no more lines. Otherwise output L lines follow. Each of the L lines should contains four distinct integers x, y, z and w, indicating a 2-switch on G, as described.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;   For some reason, if L is equal to or larger than 1000000, ivankevin would think the switch sequence you found is so ugly that it is ungelieveble and unacceptable. Otherwise, if L < 1000000 and the sequence finally transform G into H, he will accept your answer. Sample Input 4 0 1 0 0 1 0 0 0 0 0 0 1 0 0 1 0 0 0 1 0 0 0 0 1 1 0 0 0 0 1 0 0 4 0 1 0 0 1 0 0 0 0 0 0 1 0 0 1 0 0 1 1 0 1 0 0 0 1 0 0 0 0 0 0 0 Sample Output 1 0 1 3 2 -1
