PAT 1086 Tree Traversals Again 题目: An inorder binary tree traversal can be implemented in a non-recursive way with a stack. For example, suppose that when a 6-node binary tree (with the keys numbered from 1 to 6) is traversed, the stack operations ar…
做作业的时候,邻座的小盆友问你:“五乘以七等于多少?”你应该不失礼貌地围笑着告诉他:“五十三.”本题就要求你,对任何一对给定的正整数,倒着输出它们的乘积. 输入格式: 输入在第一行给出两个不超过 1000 的正整数 A 和 B,其间以空格分隔. 输出格式: 在一行中倒着输出 A 和 B 的乘积. 输入样例: 5 7 输出样例: 53 #include <iostream> using namespace std; int main(){ int a,b,tmp;string res="…
