L is the number of levels making up the dungeon. R and C are the number of rows and columns making up the plan of each level. Then there will follow L blocks of R lines each containing C characters. Each character describes one cell of the dungeon. A cell full of rock is indicated ...
n 皇后问题研究的是如何将 n 个皇后放置在 n×n 的棋盘上,并且使皇后彼此之间不能相互攻击。 上图为 8 皇后问题的一种解法。 给定一个整数 n,返回所有不同的 n 皇后问题的解决方案。 每一种解法包含一个明确的 n 皇后问题的棋子放置方案,该方案中 'Q' 和 '.' 分别代表了皇后和空位。 示例: 输入: 4...

2. Trapped! 题目分析其实这是一道简单的三维BFS的题目,相比较与其他二维BFS迷宫问题,三维只是多加了一个楼层,那么我们就把二维转化为三维,其他的与二维迷宫差不了太多。详细解释在代码中,我已经解释得很详尽了,希望各位可以听懂。 #include <iostream>#include <algorithm>#include <cstdio>#include <cstring>using...
