(3)在迷宫中探索路线的同时就把路线保存在 predecessor 数组中,已经走过的点在 maze 数组中记为2防止重复走,最后找到终点时就根据 predecessor 数组保存的路线从终点打印到起点 (4)伪代码(Pseudocode)如下 (5)DFS的特点如下: 每次探索完各个方向相邻的点之后,取其中一个相邻的点走下去,一直走到无路可走了再退回...
Fortunately, all of these operations are supported by a double ended queue (or deque in C++ STL). Let's have a look at pseudocode for this trick : forall vinvertices:dist[v]=inf dist[source]=0;deque d d.push_front(source)whiled.empty()==false:vertex=getfront elementandpopasinBFS.for...
