This article mainly introduces how to solve the same tree problem of leetcode tree, which is very detailed and has certain reference value. Friends who are interested must finish reading it!

Given two binary trees, write a function to verify whether they are the same. If two trees are structurally identical and the nodes have the same value, they are considered to be the same. Example 1: input: 1 1 /\ /\ 2 3 2 3 [1 magi 2, 3 3], [1 recital 2, 3] output: true example 2: input: 1 1 /\ 2 [1 # 2], [1 recital null] 2] output: false example 3: input: 1 1 /\ /\ 2 1 1 2 [1 Magi 2 1], [1 Magi 1 2] output: false Source: LeetCode Link: https://leetcode-cn.com/problems/same-tree copyright belongs to the collar buckle network.
