Given a binary tree, find its maximum depth.
The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node.
求二叉樹的最大深度問題用到深度優先搜尋DFS,遞歸的完美應用,跟求二叉樹的最小深度問題原理相同。代碼如下:
C++ 解法一:
<a>class Solution {</a>
Java 解法一:
我們也可以使用層序周遊二叉樹,然後計數總層數,即為二叉樹的最大深度,參見代碼如下:
C++ 解法二:
Java 解法二:
<a>public class Solution {</a>
