《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...
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...

1.In a binary search tree, the keys on the same level from left to right must be in sorted (non-decreasing) order. True; 2.In a binary search tree which contains several integer keys including 4, 5, and 6, if 4 and 6 are on the same level, then 5 must be their parent. False...
[22] argue that merging more than two runs at once is beneficial, while using a tree of binary merges to perform the merge. Like ping-pong merge, all these techniques use binary merges instead of heaps, but focus on taking advantage of multiple cores and processor-specific features such as...
