LeetCode104_MaximumDepthofBinaryTree Java题解

题目：

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.

求最大深度  和前面一题类似  用递归遍历就能够

代码：

public static int maxDepth(TreeNode root) {
		if(root==null)//递归返回或结束条件
			return 0;
		else {
			return 1+Math.max(maxDepth(root.left),maxDepth(root.right) );
		}
        
    }
