TwoFour 不会求解
Description The members of the National Informatics Team are very proud of the new game they invented, that they called similarly to a problem from the International Olympiad in Informatics from the last year, which they liked very much. So, the game is called TwoFour. In this game, N piles are used, each one containing at least 0 and at most 4 beeds. The total number of beeds from all the piles is 2*N. Two players move alternatively, each player, in his turn, being forced to do a valid move. In a valid move the player chooses 2 piles, the first pile having more beeds than the second pile. The player takes a beed from the first pile and moves it into the second one. The move is considered valid only if the number of beeds resulted in the second pile after the move of the beed is not bigger than the number of beeds left in the first pile. The game is over when there isn't any valid move (if you think a little, you will see that this thing happens when each pile has 2 beeds). The winner of the game is considered to be the one who has more piles at the end of the game. Of course, if both players own an equal number of piles the game is considered to be even. A player owns a pile if the pile has 2 beeds, and this number (of two beeds) resulted after a move made by that player. For example, if a player chooses a pile with 4 beeds and a pile with one beed, after the move, he owns the second pile (which will have 2 beeds), but the first pile does not belong yet to anybody. If he chooses a pile with 3 beeds and a pile with 0 beeds, the player will become the owner of the first pile, because, after the move that he made, that pile will remain with 2 beeds. In case he chooses a pile with 3 beeds and a pile with one beed after he makes a move he will own the both piles (both have now two beeds). If a player is the owner of a pile at a certain moment during the game, it doesn't mean that this pile will remain in his possession until the end. For example, let's suppose that the player no. 1 owns a pile with two beeds and it is the second's player turn. If he chooses a pile with 4 beeds and the pile with 2 beeds that belongs to the player no. 1, after this move, the both piles will have 3 beeds, and the number of piles that are in the no. 1 player's possession will decrease with 1 (the pile formerly owned by him doesn't belong to any of the two players because it doesn't have 2 beeds). If the initial configuration of the game contains some piles having two beeds, these ones are equally distributed to the two players. If the number of piles with two beeds is odd, then player no. 2 will receive a pile more than the player no.1. The player no. 1 is the one who makes the first move. Write a program that for a given N and a set of initial configurations of the game with N piles, decides the result of each game configuration. Input On the first line of the input are two integers: N (3 <= N <= 30) and S (1 <= S <= 1000), representing the number of piles used in the game and the number of initial configurations of game, described in the following lines. Each of the next S lines contains N integer values from the interval [0, 4] which sum is 2*N, representing an initial configuration of the game. Output In the output, for each initial configuration of the game described in the input file, in the order they are described, write the final result of the game in the conditions that both players play optimal. If the first player wins, you should write the value 1; if the second player wins, you should write the value 2; else (even game) the value to be written is 0.

A Brief Gerrymander
Description The evil ruling party, the Liberatives, are redistributing the electoral regions (ridings) in your city, and are nefariously attempting to pack certain opposition-friendly neighborhoods into as few ridings as possible. If this plan succeeds, it will be the end of democracy as we know it! As a card-carrying member of the noble, compassionate Conservals (the main opposition party), you must foil their devious plot and safeguard the future of our country. Under the new plan, the city will be divided up into a grid of rectangles by selecting certain major streets and avenues as boundaries. All streets and avenues stretch straight across the city, and are numbered starting from the southwest corner of the city. The city is bounded by four roads: 1st Street (west edge), 100th Street (east edge), 1st Avenue (south edge), 100th Avenue (north edge). Clearly these four roads must represent district boundaries; however, only a subset of the streets and avenues in between will divide districts. The Liberatives have already been able to fix the North-South (street) boundaries; however, they have been forced to allow the Conservals to select the East-West (avenue) boundaries. You know the location of all the opposition-friendly neighborhoods, which vote strongly Conserval. A neighborhood is exactly one block between adjacent streets and avenues. For instance, one neighborhood might lie between 47th and 48th Street and 67th and 68th Avenue. Place the avenue boundaries so that as many ridings as possible contain at least one opposition-friendly neighborhood. Input Input consists of multiple cases, each describing a city. The first line will give N, the number of Conserval neighborhoods in the city; the following N lines will contain the street and avenue number of the southwest corner of each neighborhood. The next line will contain S, the number of street boundaries, and the S street numbers that they lie on, in increasing order. The final line will consist of A (at least 2), the number of avenue boundaries you must place. Input will be terminated by a line containing -1. Output For each case, output a single line giving A followed by A distinct avenue numbers for the optimal redistriubution, in increasing order. If there are multiple such solutions, any one will do. Sample Input 2 49 49 50 50 2 1 100 3 -1 Sample Output 3 1 50 100

Balance 平衡的问题
Description Gigel has a strange "balance" and he wants to poise it. Actually, the device is different from any other ordinary balance. It orders two arms of negligible weight and each arm's length is 15. Some hooks are attached to these arms and Gigel wants to hang up some weights from his collection of G weights (1 <= G <= 20) knowing that these weights have distinct values in the range 1..25. Gigel may droop any weight of any hook but he is forced to use all the weights. Finally, Gigel managed to balance the device using the experience he gained at the National Olympiad in Informatics. Now he would like to know in how many ways the device can be balanced. Knowing the repartition of the hooks and the set of the weights write a program that calculates the number of possibilities to balance the device. It is guaranteed that will exist at least one solution for each test case at the evaluation. Input The input has the following structure: • the first line contains the number C (2 <= C <= 20) and the number G (2 <= G <= 20); • the next line contains C integer numbers (these numbers are also distinct and sorted in ascending order) in the range -15..15 representing the repartition of the hooks; each number represents the position relative to the center of the balance on the X axis (when no weights are attached the device is balanced and lined up to the X axis; the absolute value of the distances represents the distance between the hook and the balance center and the sign of the numbers determines the arm of the balance to which the hook is attached: '-' for the left arm and '+' for the right arm); • on the next line there are G natural, distinct and sorted in ascending order numbers in the range 1..25 representing the weights' values. Output The output contains the number M representing the number of possibilities to poise the balance. Sample Input 2 4 -2 3 3 4 5 8 Sample Output 2

A Brief Gerrymander 实现原理
Description The evil ruling party, the Liberatives, are redistributing the electoral regions (ridings) in your city, and are nefariously attempting to pack certain opposition-friendly neighborhoods into as few ridings as possible. If this plan succeeds, it will be the end of democracy as we know it! As a card-carrying member of the noble, compassionate Conservals (the main opposition party), you must foil their devious plot and safeguard the future of our country. Under the new plan, the city will be divided up into a grid of rectangles by selecting certain major streets and avenues as boundaries. All streets and avenues stretch straight across the city, and are numbered starting from the southwest corner of the city. The city is bounded by four roads: 1st Street (west edge), 100th Street (east edge), 1st Avenue (south edge), 100th Avenue (north edge). Clearly these four roads must represent district boundaries; however, only a subset of the streets and avenues in between will divide districts. The Liberatives have already been able to fix the North-South (street) boundaries; however, they have been forced to allow the Conservals to select the East-West (avenue) boundaries. You know the location of all the opposition-friendly neighborhoods, which vote strongly Conserval. A neighborhood is exactly one block between adjacent streets and avenues. For instance, one neighborhood might lie between 47th and 48th Street and 67th and 68th Avenue. Place the avenue boundaries so that as many ridings as possible contain at least one opposition-friendly neighborhood. Input Input consists of multiple cases, each describing a city. The first line will give N, the number of Conserval neighborhoods in the city; the following N lines will contain the street and avenue number of the southwest corner of each neighborhood. The next line will contain S, the number of street boundaries, and the S street numbers that they lie on, in increasing order. The final line will consist of A (at least 2), the number of avenue boundaries you must place. Input will be terminated by a line containing -1. Output For each case, output a single line giving A followed by A distinct avenue numbers for the optimal redistriubution, in increasing order. If there are multiple such solutions, any one will do. Sample Input 2 49 49 50 50 2 1 100 3 -1 Sample Output 3 1 50 100
TwoFour C语言程序设计的办法
Description The members of the National Informatics Team are very proud of the new game they invented, that they called similarly to a problem from the International Olympiad in Informatics from the last year, which they liked very much. So, the game is called TwoFour. In this game, N piles are used, each one containing at least 0 and at most 4 beeds. The total number of beeds from all the piles is 2*N. Two players move alternatively, each player, in his turn, being forced to do a valid move. In a valid move the player chooses 2 piles, the first pile having more beeds than the second pile. The player takes a beed from the first pile and moves it into the second one. The move is considered valid only if the number of beeds resulted in the second pile after the move of the beed is not bigger than the number of beeds left in the first pile. The game is over when there isn't any valid move (if you think a little, you will see that this thing happens when each pile has 2 beeds). The winner of the game is considered to be the one who has more piles at the end of the game. Of course, if both players own an equal number of piles the game is considered to be even. A player owns a pile if the pile has 2 beeds, and this number (of two beeds) resulted after a move made by that player. For example, if a player chooses a pile with 4 beeds and a pile with one beed, after the move, he owns the second pile (which will have 2 beeds), but the first pile does not belong yet to anybody. If he chooses a pile with 3 beeds and a pile with 0 beeds, the player will become the owner of the first pile, because, after the move that he made, that pile will remain with 2 beeds. In case he chooses a pile with 3 beeds and a pile with one beed after he makes a move he will own the both piles (both have now two beeds). If a player is the owner of a pile at a certain moment during the game, it doesn't mean that this pile will remain in his possession until the end. For example, let's suppose that the player no. 1 owns a pile with two beeds and it is the second's player turn. If he chooses a pile with 4 beeds and the pile with 2 beeds that belongs to the player no. 1, after this move, the both piles will have 3 beeds, and the number of piles that are in the no. 1 player's possession will decrease with 1 (the pile formerly owned by him doesn't belong to any of the two players because it doesn't have 2 beeds). If the initial configuration of the game contains some piles having two beeds, these ones are equally distributed to the two players. If the number of piles with two beeds is odd, then player no. 2 will receive a pile more than the player no.1. The player no. 1 is the one who makes the first move. Write a program that for a given N and a set of initial configurations of the game with N piles, decides the result of each game configuration. Input On the first line of the input are two integers: N (3 <= N <= 30) and S (1 <= S <= 1000), representing the number of piles used in the game and the number of initial configurations of game, described in the following lines. Each of the next S lines contains N integer values from the interval [0, 4] which sum is 2*N, representing an initial configuration of the game. Output In the output, for each initial configuration of the game described in the input file, in the order they are described, write the final result of the game in the conditions that both players play optimal. If the first player wins, you should write the value 1; if the second player wins, you should write the value 2; else (even game) the value to be written is 0. Sample Input 5 4 0 3 4 1 2 2 2 2 2 2 1 1 2 2 4 4 3 2 1 0 Sample Output 1 2 1 1

Queen’s Case用C语言来做
Problem Description A small country called Maltius was governed by a queen. The queen was known as an oppressive ruler.People in the country suffered from heavy taxes and forced labor. So some young people decided to form a revolutionary army and fight against the queen. Now, they besieged the palace and have just rushed into the entrance. Your task is to write a program to determine whether the queen can escape or will be caught by the army. Here is detailed description. ● The palace can be considered as grid squares. ● The queen and the army move alternately. The queen moves first. ● At each of their turns, they either move to an adjacent cell or stay at the same cell. ● Each of them must follow the optimal strategy. ● If the queen and the army are at the same cell, the queen will be caught by the army immediately. ● If the queen is at any of exit cells alone after the army’s turn, the queen can escape from the army. ● There may be cases in which the queen cannot escape but won’t be caught by the army forever, under their optimal strategies. Input The input describes a map of the palace. The first line of the input contains two integers W (1 <= W <= 30) and H (1 <=H <= 30), which indicate the width and height of the palace. The following H lines, each of which contains W characters, denote the map of the palace. “Q” indicates the queen,“A” the army,“E” an exit,“#” a wall and “.” a floor. The map contains exactly one “Q”, exactly one “A” and at least one “E”. You can assume both the queen and the army can reach all the exits Output Output “Queen can escape.”, “Army can catch Queen.” or “Queen can not escape and Army can not catch Queen.” in a line. Sample Input 2 2 QE EA 3 1 QAE 3 1 AQE 5 5 ..E.. .###. A###Q .###. ..E.. 5 1 A.E.Q 5 5 A.... ####. ..E.. .#### ....Q Sample Output Queen can not escape and Army can not catch Queen. Army can catch Queen. Queen can escape. Queen can not escape and Army can not catch Queen. Army can catch Queen. Army can catch Queen.

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
