当树更平衡时,bfs的空间开销可能更大,当树偏斜时,dfs的空间开销可能更大; 4. 选择哪一种遍历方式的考虑: 空间开销 dfs一般是递归实现,需要函数调用开销 bfs是从根开始遍历,dfs一般是从叶节点开始遍历,所以看问题需求 参考链接:https://www.geeksforgeeks.org/bfs-vs-dfs-binary-tree/...

这让我想到了leetcode上面经典的一道算法题目Maximum Depth of Binary Tree 题目是这样的: 给定一个二叉树,找出其最大深度。 二叉树的深度为根节点到最远叶子节点的最长路径上的节点数。 比如上面这棵树,最大深度是4。 迭代乃人工,递归方神通 To iterate is human, to recurse, divine 这道题有很多种的解...
current height from 1 to h (height of the tree). Use DFS to traverse the tree and maintain height for the current node. If the Node is NULL then return; If level is 1 print(tree->data); Else if the level is greater than 1, then Recursively call to for tree->left, level-1. ...
