Given two binary trees and imagine that when you put one of them to cover the other, some nodes of the two trees are overlapped while the others are not. You need to merge them into a new binary tree. The merge rule is that if two nodes overlap, then sum node values up as the ne...

《669. Trim a Binary Search Tree》的核心比较容易想:首先是一棵搜索树,其次在边界条件整棵子树都能砍掉;(其实,Merge的核心思路也类似,一时间没联想到) 5,树高完成后,该问题顺利AC,但凭经验肯定是山路十八弯。再回到最初的递归解法,因为有树高的热身,再次回到问题本身的时候,竟然思路顺利很多。但仍然在函数...

一、题目描述 给定两个二叉树,想象当你将它们中的一个覆盖到另一个上时,两个二叉树的一些节点便会重叠。你需要将他们合并为一个新的二叉树。合并的规则是如果两个节点重叠,那么将他们...
This option is a more advanced form ofsubtreestrategy, where the strategy makes a guess on how two trees must be shifted to match with each other when merging. Instead, the specified path is prefixed (or stripped from the beginning) to make the shape of two trees to match. ...
