Now it's your turn to prove that YOU CAN invert a binary tree! Input Specification: Each input file contains one test case. For each case, the first line gives a positive integer N (≤10) which is the total number of nodes in the tree -- and hence the nodes are numbered from 0 t...

这道题关于倒置树/镜像树的思路其实在1043 Is It a Binary Search Tree,关键就是通过不建树,改变子节点遍历顺序的方法来输出倒置顺序。 另外就是多了个查找根节点的环节,这个只要从头到尾逐个找就好了。 #include<iostream>#include<stdio.h>#include<queue>usingnamespacestd;structNode{intleft,right;}Trees[20...
Invert the Binary Tree | Problem Description Given a binary tree A, invert the binary tree and return it. Inverting refers to making left child as the right child and vice versa. Problem Constraints 1 <= size of tree <= 100000 Input Format First and only
