[Leetcode] Same Tree (Java)

Given two binary trees, write a function to check if they are equal or not.

Two binary trees are considered equal if they are structurally identical and the nodes have the same value.

判断两颗树是否相同，碰到的最简单的题

public class Solution {    public boolean isSameTree(TreeNode p, TreeNode q) {        if(p==null&&q==null)return true;if(p==null||q==null)return false;return p.val==q.val&&isSameTree(p.left, q.left)&&isSameTree(p.right, q.right);            }}
