LeetCode - Maximum Depth of Binary Tree
递归求二叉树的最大深度。
/** * Definition for binary tree * public class TreeNode { * int val; * TreeNode left; * TreeNode right; * TreeNode(int x) { val = x; } * } */ public class Solution { public int maxDepth(TreeNode root) { if(root == null) return 0; if(root == null) return 0; int l = maxDepth(root.left); int r = maxDepth(root.right); if(l > r) return l+1; else return r+1; } }
