归并排序(merge sort)是一个时间复杂度为O(nlogn)的基于比较的排序算法(comparison based sorting algorithm)。 归并排序大多数实现(implementation)都将其实现成了一个stable sort, 所谓的stable sort的意思就是the implementation preserves the input order of equal...

这道题运用了置换的知识。
题目大意:
用两两交换的方式给一个数列排序,每交换一次的代价是这两个数之和求最小代价。
解题思路:
对于这种情况,我们在数列中找置换环。每个置换环内的数都是可以回归到它应有的位置上并且不影响其他的置换环。
置换环归位的代价有两种,第一种是用环内最小的数与其他数交换,另一种是用整个数列中最小的数与环内最小的数交换,完成环内所有数的归位后在换...
