1.寻找最短路径BFS可以用于寻找两个节点之间的最短路径。它首先探索起点的所有相邻节点，然后逐层向外扩展，直到找到终点。以下是使用Python实现BFS寻找最短路径的示例代码：def bfs_shortest_path(graph, start, end): queue = [(start, [start])] while queue: (node,
4. 代码理解图 理解: (1)首先设置了(r, c)=(0, 0)作为起始点,也就是数字为1的位置,接下来,我们要想它能往那里走呢?常识告诉我们,它只有(右,下)两条路可以走,那么看看代码,它满足 check 添加 R 和 D 的条件,所以确实和我们想的 一样。 (2)如果check不为空,那么就可以随机选择一个方向走,我们1...

In this tutorial, you will learn about Depth First Search in C with the algorithm and program examples. Most graph problems involve the traversal of a graph. Traversal of a graph means visiting each node and visiting exactly once. There are two types of
