For example, [1,2,3]have the following permutations: [ [1,2,3], [1,3,2], [2,1,3], [2,3,1], [3,1,2], [3,2,1] ] 这道题目是全排列的题目,也就是排列组合,最常用的方法是递归,这里要注意的是,并不是从前往后单方向的推进,前面的数也可以放在后面。因此在递归循环中,需要对全部元...

Given integers nn and mm, Jongwon wants to compute the sum of happiness for all permutations of length nn, modulo the prime number mm. Note that there exist n!n! (factorial of nn) different permutations of length nn. Input The only line contains two integers nn and mm (1≤n≤2500001≤...
S1的学习包括representation of data,permutations,combinations,normal distribution等。关于S1,众说纷纭,有的人认为简单,根本不需要多少练习就能拿到满分。也有人(比如我),即使练了很多题也没有完全摸清楚规律,最后扣的分竟然比P3还多。考试题目有7道题,...
