Cards in this deck (1)
- 1Given two binary trees, write a function to check if they are the same or not. Two binary trees are considered the same if they are structurally identical and the nodes have the same value./**
* Definition for a binary tree node.
* public class TreeNode {
* int val;
* TreeNode left;
* TreeNode right;
* TreeNode(int x) { val = x; }
* }
*/
class Solution {
public boolean isSameTree(TreeNode p, TreeNode q) {
if( p == null && q == null ) return true;
if( p == null || q == null )
return false;
if( p.val == q.val)
return isSameTree(p.left,q.left) && isSameTree(p.right,q.right);
return false;
}
}
