题目地址 http://codeforces.com/contest/504/problem/B    这道题目让我更深入的了解了康拓展开。以前只是在做8数码的时候接触了康拓展开了。在比赛的时候想到了康拓展开，但是不知道怎么逆展开，所以没做出来。先介绍一下康拓展开。康拓展开：把一个排列展开成如下形式：X=a[n]*(n-1)!+a[n-1]*(n-2)!+...+a[i]*(i-1)!+...+a

STL全排列算法next_permutation和prev_permutation

    全排列的问题取决于如何找到“下一个”，然后就用同样的方法找到全部的排列   全排列这个问题其实和我们数数：11,12,13,14,15,16,17,18,19,20,21，一样的规律，只不过他的变化只要那固定的几个数自每次都出现，这就导致我们传统的连续整数会在那里丢失一部分；你如何对剩下的这些全排列中的数字看成是“连续的”一列数字，对于“第一个”“最小的数字”找到它的“下一个”，然后用同样
