笔试题73. LeetCode OJ (60)

  PermutationSequence  这个题是求1~n(n[1~9])的数字的全排列的第K个序列。  一般思路是：使用一个计数器，递归去找全排列序列，找到一个计数器加一，一直到第k个。

参考地址 http://www.mamicode.com/info-detail-650903.html首先，关于什么是全排列不做解释。如果一个排列为A，下一个排列为A_NEXT，那么A_NEXT一定与A有尽可能长的公共前缀。看具体例子，一个排列为124653，如何找到它的下一个排列，因为下一个排列一定与124653有尽可能长的前缀，所以，脑洞大开一下，从后面往前看这个序列，如果后面的若干个数字有

C++标准库中next_permutation和pre_permutation实现原理

标准库中next_permutation函数：找当前序列中元素排列的下一个排列，按照字典顺序进行排列。比如说数组排列"123"，那么它的下一个排列为"132"，并且返回true。
