BFS算法(Breadth-First Search,广度优先搜索)是一种常用的图搜索算法,用于解决两个节点之间的最短路径问题。 BFS算法从起点开始遍历图,一层层地扩展搜索,直到找到目标节点或者搜索完整张图。在搜索过程中,BFS算法会先遍历起点相邻的所有节点,然后再遍历这些节点相邻的所有节点,以此类推,直到找到目标节点或者遍历完整张...

广度优先搜索(Breadth First Search,简称bfs)是属于图论的一种,广泛应用于数据结构的搜索,通常用于解决一些最短路径的问题。 广度优先搜索的核心思路是:确定一个或多个源点,以这些源点为起点向外发散,确定下一步可能会走到的所有点(必要时可使用哈希去重,记录走过的点,因为有些时候bfs可能会进入死循环,并且可以验...
