Young's Picture Permutations

题目描述有1～N1～N共NN个数字，让你排成kk排，要求第ii排有AiAi个数字，同时满足每排上的数字单调递增，每列上的数字单调递增，求合法的方案数。N≤30,k≤5N≤30,k≤5。吐槽这个题书上的做法就是动态规划，想着很多状态用不到就写了个记忆化搜索，一边过样例，结果交上去MLE了，转眼看内存限制居然才64MB64MB，搜网上的题解也基本上是用数学方法，但是我不会啊，所以灵机一动，用mallo

构造法——Diverse Permutation ( CodeForces 482A )

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
