Here I will introduce the breadth first traversal of binary tree. The principe is that you traverse the binary tree level by level. This traversal is quite different than depth first traversal. In depth first traversal you can use recursive method to traverse. Here is one solution using a que...
And as @Patrick noted, a binary tree backed by an array is typically stored in breadth-first traversal order anyway, so a breadth-first search on that would be trivial, also without needing an auxiliary queue. Share Improve this answer Follow edited May 23, 2017 at 12:02 CommunityBot 111...

上次在介绍完功能强大的深度优先搜索算法(DFS)后,这次我来给大家介绍一下另一个功能类似且同样强大的经典算法——广度优先搜索算法 Breadth-First-Search(BFS)。 I. 算法定义 BFS同DFS一样,是一种用于遍历、搜索树或图的一种搜索算法。与DFS会先一路走到黑不同,BFS会从根节点开始搜索,在每一个路口面临分叉的...

Breadth–first search (BFS)is a graph traversal algorithm that explores vertices in the order of their distance from the source vertex, where distance is the minimum length of a path from the source vertex to the node as evident from the above example. ...
