There is a classical process named partition in the famous quick sort algorithm. In this process we typically choose one element as the pivot. Then the elements less than the pivot are moved to its left and those larger than the pivot to its right. G…

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(<=100000),接着输入N个正整数(0~N-1的排列).每次操作可以将0和另一个数的位置进行交换,输出最少操作次数使得排列为升序. AAAAAccepted code: #define HAVE_STRUCT_TIMESPEC #include<bits/stdc++.h> using namespace std; ],b[]; int main(){ ios::sync_with_stdio(false); cin.tie(NULL); cout.tie(…

PAT甲级1098. Insertion or Heap Sort 题意: 根据维基百科: 插入排序迭代,消耗一个输入元素每次重复,并增加排序的输出列表.在每次迭代中,插入排序从输入数据中删除一个元素,在排序列表中找到它所属的位置,并将其插入到其中.它重复,直到没有输入元素保留. 堆排序将其输入分成排序和未排序的区域,并且通过提取最大的元素并将其移动到排序的区域来迭代地缩小未排序的区域.它涉及使用堆数据结构而不是线性时间搜索来查找最大值. 现在给出整数的初始序列, 连同一些序列,这是一些排序方法…
