描述 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. 分析 递归版 // Same Tree // 递归版,时间复杂度O(n),空间复杂度O(logn) public class Solution { p...

The "deepest node" of the example isn't 'd', but 'd' is the value of the deepest node. Interviewers should be clear, in my opinion.This is a question for an entry-level position interview. It involves a traverse of a binary tree where the value of the nodes is only for ...
