生成1到n的全排列，字典序由小到大打印

【A】排列，一般地，从n个不同元素中取出m（m≤n）个元素，按照一定的顺序排成一列，叫做从n个元素中取出m个元素的一个排列(permutation)。

算法23 Permutation Sequence

题目：该集合共包含n！独特的排列。[1,2,3,…,n]通过按顺序列出和标记所有的排列，我们得到以下序列（即n=3）："123""132""213""231""312""321"给定n和k，返回第k个排列序列。注：鉴于n将在1和9之间。思路：从阶乘的基本规律我们可以看到对于数字n来说，从1到n的每个数字开头的排列有(n-1)!个。就像前面这样，以1,2,3,4分别开头的排列它们每个都是有6个。因此
