  无线电网络 题目大意:就是地震后,所有的电脑都坏了,现在可以修复,而且要重新连成一个网络,两台电脑之间最大连接距离为D,两台电脑可以有中继电脑,按O修复电脑,按S测试两台电脑是否有链接,如果有就输出SUCCESS,不行就FAIL 一看到电脑,我就联想到了查并集,这一题也不例外,我们维护在距离内的查并集就可以了,具体思路不难,每一次修复都扫描所有的节点看能否连接即可 #include <iostream> #include <functional> #include <al…

题目大意:有n台坏掉的电脑,给出每台电脑的坐标,然后每次询问输入0(字符) x,表示电脑x恢复正常,输入S x y 询问x和y是否可以联网.只要是x和y的距离小于距离d,那么就可以联网,如果有个中介c使得x到c的距离小于d,y到c的距离小于d,那么x和y也可以联网. 题解:当修复好一台电脑后,然后判断与之前修好的电脑的距离,小于d的话,用并查集连在一起.(没敢这样想,感觉这样会T....) #include<cstdio> #include<iostream> #include&l…

定义一个二维数组: int maze[5][5] = { 0, 1, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 1, 0, }; 它表示一个迷宫,其中的1表示墙壁,0表示可以走的路,只能横着走或竖着走,不能斜着走,要求编程序找出从左上角到右下角的最短路线. Input 一个5 × 5的二维数组,表示一个迷宫.数据保证有唯一解. Output 左上角到右下角的最短路径,格式如样例所示. Sample Input 0…

Farmer John has been informed of the location of a fugitive cow and wants to catch her immediately. He starts at a point N (0 ≤ N ≤ 100,000) on a number line and the cow is at a point K (0 ≤ K ≤ 100,000) on the same number line. Farmer John has two m…

You are trapped in a 3D dungeon and need to find the quickest way out! The dungeon is composed of unit cubes which may or may not be filled with rock. It takes one minute to move one unit north, south, east, west, up or down. You cannot move diagonal…

在一个给定形状的棋盘(形状可能是不规则的)上面摆放棋子,棋子没有区别.要求摆放时任意的两个棋子不能放在棋盘中的同一行或者同一列,请编程求解对于给定形状和大小的棋盘,摆放k个棋子的所有可行的摆放方案C. Input 输入含有多组测试数据. 每组数据的第一行是两个正整数,n k,用一个空格隔开,表示了将在一个n*n的矩阵内描述棋盘,以及摆放棋子的数目. n <= 8 , k <= n 当为-1 -1时表示输入结束. 随后的n行描述了棋盘的形状:每行有n个字符,其中 # 表示棋盘区域, . 表示空白…
