A+B in Hogwarts

If you are a fan of Harry Potter, you would know the world of magic has its own currency system -- as Hagrid explained it to Harry, "Seventeen silver Sickles to a Galleon and twenty-nine Knuts to a Sickle, it's easy enough." Your job is to write a program to compute A+B where A and B are given in the standard form of "Galleon.Sickle.Knut" (Galleon is an integer in [0, 107], Sickle is an integer in [0, 17), and Knut is an integer in [0, 29)).

Input Specification:

Each input file contains one test case which occupies a line with A and B in the standard form, separated by one space.

Output Specification:

For each test case you should output the sum of A and B in one line, with the same format as the input.

Sample Input:
3.2.1 10.16.27
Sample Output:
14.1.28

Harry Potter and the Binary Kingdom

问题描述 : After defeating the Voldemort, Harry is enjoying his senior year in Hogwarts with his friends. They decide to make a graduation trip, using their newest magical broom. In the journey, Harry is trapped in a Kingdom named Binary Kingdom, maybe because the smart but isolated people still have no idea of the great reputation of this young wizard. Loving numbers and binary very much, the subjects of Binary Kingdom claim only Harry solve the problem can he leave there. Harry Potter and J.K.Rowling The problem begins with an empty number multi-set, with six kinds of operation: 1. INS M: insert M into the set 2. DEL M: delete all numbers equal to M if any one exists; otherwise report “Del error” 3. ADD M: increase the value of every number by M 4. SUB M: decrease the value of every number by M if after decreasing no number will be less than zero; otherwise report “Sub error” 5. QNUM M: query how many numbers equal to M in the set 6. QBIT M: query how many numbers whose M-th bit is 1 in its binary, M is counting from lower to higher, beginning with 0 Though our brave Harry Potter can proficient in many fields, he is not good at math, now, it’s your time. 输入: The first line contains a single integer T, indicating the number of test cases. Each test case begins with an integer M, following M operations. Technical Specification 1. 1 <= T <= 12 2. 1 <= M <= 100 000 3. The QBIT operations’ M will in the range [0, 17], the other five operations’ M in the range [0, 1 000 000 000]. 输出: The first line contains a single integer T, indicating the number of test cases. Each test case begins with an integer M, following M operations. Technical Specification 1. 1 <= T <= 12 2. 1 <= M <= 100 000 3. The QBIT operations’ M will in the range [0, 17], the other five operations’ M in the range [0, 1 000 000 000]. 样例输入: 1 10 INS 1 INS 2 DEL 1 INS 3 DEL 1 ADD 1 SUB 4 QNUM 2 QBIT 1 QBIT 2 样例输出: Case 1: Del error Sub error 0 1 1

Stealing Harry Potter's Precious

Problem Description   Harry Potter has some precious. For example, his invisible robe, his wand and his owl. When Hogwarts school is in holiday, Harry Potter has to go back to uncle Vernon's home. But he can't bring his precious with him. As you know, uncle Vernon never allows such magic things in his house. So Harry has to deposit his precious in the Gringotts Wizarding Bank which is owned by some goblins. The bank can be considered as a N × M grid consisting of N × M rooms. Each room has a coordinate. The coordinates of the upper-left room is (1,1) , the down-right room is (N,M) and the room below the upper-left room is (2,1)..... A 3×4 bank grid is shown below:   Some rooms are indestructible and some rooms are vulnerable. Goblins always care more about their own safety than their customers' properties, so they live in the indestructible rooms and put customers' properties in vulnerable rooms. Harry Potter's precious are also put in some vulnerable rooms. Dudely wants to steal Harry's things this holiday. He gets the most advanced drilling machine from his father, uncle Vernon, and drills into the bank. But he can only pass though the vulnerable rooms. He can't access the indestructible rooms. He starts from a certain vulnerable room, and then moves in four directions: north, east, south and west. Dudely knows where Harry's precious are. He wants to collect all Harry's precious by as less steps as possible. Moving from one room to another adjacent room is called a 'step'. Dudely doesn't want to get out of the bank before he collects all Harry's things. Dudely is stupid.He pay you $1,000,000 to figure out at least how many steps he must take to get all Harry's precious. Input   There are several test cases.   In each test cases:   The first line are two integers N and M, meaning that the bank is a N × M grid(0<N,M <= 100).   Then a N×M matrix follows. Each element is a letter standing for a room. '#' means a indestructible room, '.' means a vulnerable room, and the only '@' means the vulnerable room from which Dudely starts to move.   The next line is an integer K ( 0 < K <= 4), indicating there are K Harry Potter's precious in the bank.   In next K lines, each line describes the position of a Harry Potter's precious by two integers X and Y, meaning that there is a precious in room (X,Y).   The input ends with N = 0 and M = 0 Output   For each test case, print the minimum number of steps Dudely must take. If Dudely can't get all Harry's things, print -1. Sample Input 2 3 ##@ #.# 1 2 2 4 4 #@## .... #### .... 2 2 1 2 4 0 0 Sample Output -1 5

计算寻找哪些小岛是可以到达的,怎么采用C语言的程序编写的代码的方式去输出这些小岛呢?

Problem Description Recently, a new emerging game has become popular in Hogwarts. The goal of the game is to connect all islands in the ground with rainbows. At the beginning, n islands are isolated and the player arrive at the first island. There is a red magic set and a blue magic set on each island. Once the players of the game arrive at one of the islands, they will follow the sequence, which is firstly entering the red magic set, then the blue one. When a player enters the red magic set, he/she has the possibility of p to gain a rainbow, thereby two random island of all will be connected by the rainbow(including which two have been connected). When a player enters the blue magic set, he/she will be sent to one of the s islands with same possibility. One unit of total magic volume will be expended when the player uses the blue magic. At the end of the game, the winner is the one who consumes the least of total magic volume. However, the brilliant Hermione despises the game, she wants to know the expected magic volume to be taken away the goal of the game was achieved. Input There are multiply test cases. The first line contains an integer T(T<=100), indicates the number of cases. For each case the first line contains an integer n, indicates the number of the islands. (1<=n<=20) Then there will be n numbers, pi indicates the possibility to gain a rainbow for the i-th island. (0<pi<1) The next n lines, each line firstly contains an integer s, then followed by s integers, indicates the number of which the i-th island can arrive at. (1 <= s <= n) Output For each test case, you should output “Case #K: “ first, where K indicates the case number and counts from 1. Then output the answer. Round the answer to the sixth digit after the decimal point. Sample Input 2 3 0.123 0.984 0.63 2 1 2 2 2 3 2 1 3 2 0.75 0.34 2 1 2 2 1 2 Sample Output Case #1: 4.931167 Case #2: 1.458716

数据结构问题,诡异的楼梯帮助寻找路线如何利用C语言高效实现的呢

Problem Description Hogwarts正式开学以后,Harry发现在Hogwarts里,某些楼梯并不是静止不动的,相反,他们每隔一分钟就变动一次方向. 比如下面的例子里,一开始楼梯在竖直方向,一分钟以后它移动到了水平方向,再过一分钟它又回到了竖直方向.Harry发现对他来说很难找到能使得他最快到达目的地的路线,这时Ron(Harry最好的朋友)告诉Harry正好有一个魔法道具可以帮助他寻找这样的路线,而那个魔法道具上的咒语,正是由你纂写的. Input 测试数据有多组,每组的表述如下: 第一行有两个数,M和N,接下来是一个M行N列的地图,'*'表示障碍物,'.'表示走廊,'|'或者'-'表示一个楼梯,并且标明了它在一开始时所处的位置:'|'表示的楼梯在最开始是竖直方向,'-'表示的楼梯在一开始是水平方向.地图中还有一个'S'是起点,'T'是目标,0<=M,N<=20,地图中不会出现两个相连的梯子.Harry每秒只能停留在'.'或'S'和'T'所标记的格子内. Output 只有一行,包含一个数T,表示到达目标的最短时间. 注意:Harry只能每次走到相邻的格子而不能斜走,每移动一次恰好为一分钟,并且Harry登上楼梯并经过楼梯到达对面的整个过程只需要一分钟,Harry从来不在楼梯上停留.并且每次楼梯都恰好在Harry移动完毕以后才改变方向. Sample Input 5 5 **..T **.*. ..|.. .*.*. S....
