Problem Description I have a very simple problem for you. Given two integers A and B, your job is to calculate the Sum of A + B. Input The first line of the input contains an integer T(1<=T<=20) which means the number of test cases. Then T lines fol

vjudge上题目链接:Huge Mods 附上截图: 题意不难理解,因为指数的范围太大,所以我就想是不是需要用求幂大法: AB % C = AB % phi(C) + phi(C) % C ( B > phi(C) ) 呢?后来发现确实需要用到,而且因为它有很多重指数,所以需要 dfs,深搜到最后一层后才返回,每次向上一层返回用求幂公式处理好的指数,然后本层用同样的原理去处理好当前层取模的值,并向上一层返回.欧拉函数预处理即可,这题的结束也有点卡人,我是用输入挂来处理的. #include<
