1146 Topological Order (25 分)   This is a problem given in the Graduate Entrance Exam in 2018: Which of the following is NOT a topological order obtained from the given directed graph? Now you are supposed to write a program to test each of the optio…

题意: 输入一个正整数N(<=1e5),接着输入一行N个各不相同的正整数.输出可以作为快速排序枢纽点的个数并升序输出这些点的值. trick: 测试点2格式错误原因:当答案为0时,需要换行两次…

一.技术总结 这里的一个关键就是理解调换位置排序是时,如果是元主,那么它要确保的条件就只有两个一个是,自己的位置不变,还有就是前面的元素不能有比自己大的. 二.参考代码 #include<iostream> #include<algorithm> #include<vector> using namespace std; int record[100000]; int main(){ int n, max = 0, count = 0; scanf("%d&q…

题意: 输入一个正整数N(<=100),接着输入两行N个数,表示原数组和经过一定次数排序后的数组.判断是经过插入排序还是堆排序并输出再次经过该排序后的数组(数据保证答案唯一). AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ],b[]; ][]; int main(){ ios::sync_with_stdio(false); cin.tie(NUL…

This is a problem given in the Graduate Entrance Exam in 2018: Which of the following is NOT a topological order obtained from the given directed graph? Now you are supposed to write a program to test each of the options. Input Specification: Each in…
