JZ55 二叉树的深度
使用递归
import java.util.*; /** public class TreeNode { int val = 0; TreeNode left = null; TreeNode right = null; public TreeNode(int val) { this.val = val; } } */ public class Solution { public int cursion(TreeNode root) { if(root == null) { return 0; } return Math.max(TreeDepth(root.left),TreeDepth(root.right)) + 1; } public int TreeDepth(TreeNode root) { return cursion(root); } }
