Permutation

洛谷 P1088 火星人（乱搞）

题目大意：已知有一串数字，问在原来的数字串的字典序加m后，应该输出多少解题思路：最简便的做法是用next_permutation，这个生成的全排列可以按照字典序递增，这里我用的是搜索的方法。

题目链接：http://codeforces.com/problemset/problem/482/A分析：这是一道构造法构造数学模型的题，建议先列出一定数量数据，然后从中寻找规律，建立模型。题解：如果数组长度为n，间隔数为k的话，我们可以假设k=n-1，然后列出n=4,n=5,n=6,n=7时候的数组的取值。取值的时候可以用这种方法：每次设第k个位置为1，那么它与之后元素的差值为k，然后从k位置
