输入一棵二叉树,求该树的深度。从根结点到叶结点依次经过的结点(含根、叶结点)形成树的一条路径,最长路径的长度为树的深度。
/*
public class TreeNode {
int val = 0;
TreeNode left = null;
TreeNode right = null;
public TreeNode(int val) {
this.val = val;
}
};*/
public class Solution {
public int TreeDepth(TreeNode pRoot)
{
if (pRoot == null) {
return 0;
}
int left = TreeDepth(pRoot.left);
int right = TreeDepth(pRoot.right);
return (left > right) ? (left + 1): (right + 1);
}
}
