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.
[题目解析] 这是一道很常见也很简单的题目。直接看代码吧。
private class TreeNode { int val; TreeNode left; TreeNode right; TreeNode(int x) {val = x;} } public int maxDepth(TreeNode root) { if(null == root) return 0; int leftDepth = maxDepth(root.left); int rightDepth = maxDepth(root.right); return leftDepth > rightDepth ? leftDepth+1:rightDepth+1; }
