题意: 紧密排列的方块因为摩擦力一个一个稳定地挤在一起,但当一个方块的四个邻居中,上下两个至少空缺一个,左右两个至少空缺一个,则这个方块也将掉落. 每次锤掉一个方块,求多少个方块受牵连落下. 题解: 可能掉落的方块总在刚刚掉落的方块上下左右四个方向出现,暴力bfs的话一个方块最多被访问4次,此复杂度可以接受. #include<iostream> #include<queue> #include<cstring> using namespace std; ]={,-,,…

题意: 就是给你一个n行m列的矩形,后面将会有q次操作,每次操作会输入x,y表示要击碎第x行第y列的石块,当击碎它之后还去判断一下周围石块是否牢固 如果一个石块的左右两边至少一个已经被击碎且上下也至少一个被击碎,那么这个石块就是不牢固的,可以把这个石块也击碎 对于每一对x,y:要输出一个整数表示此次操作击碎石块多少个 题解: 对于每输入的一对x,y:先判断这个点的石块还在不在了,不在就输出0,在的话标记一下,在以此处为起点开始bfs搜索,搜索过程中经过的点也要标记 再按照石块是否牢固的判断方法对…

题意: 一共有30000个箱子,刚开始时都是分开放置的.接下来会有两种操作: 1. M x y,表示把x箱子所在的一摞放到y箱子那一摞上. 2. C y,表示询问y下方有多少个箱子. 输入: 首行输入一个整数m,表示一共有m次操作. 接下来每次操作都是上面所说的两种中的一种. 输出: 每次C y,输出一个结果,每次输出占1行. 就是不知道究竟是只有一组测试样例还是有多组测试样例,不过我还是按照多组的方式写了. 题解: 这道题我自己思考了好久都没有思路,最后中忍不住去看了题解,然后被题解震惊了.…
