题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=5122 解题报告:定义一种排序算法,每一轮可以随机找一个数,把这个数与后面的比这个数小的交换,一直往后判断,直到后面没有比这个数小的,这样称为一轮,现在给定一个长度为n的序列,要你求,至少要经过多少轮,可以使这个序列成为有序的. 由于只能跟后面的数进行比较,所以我只要统计后面的数有比这个数小的数的个数就可以了.从后往前扫一遍,每次更新当前最小的. #include<cstdio> #include&…

传送门 对于错想成lis的解法,提供一组反例 1 3 4 2 5同时对于这次案例也可以观察出解法:对于每一个数,如果存在比它小的数在它后面,它势必需要移动,因为只能小的数无法向右移动,而且每一次移动都必然可以使得这个数到达正确位置,这是根据题意而得的 #include<queue> #include<cmath> #include<cstdio> #include<cstring> #include<cstdlib> #include<io…
