三个小函数 getdiv();        求因子 getsum();     求平方和 change();     转换成该进制 #include <cstdio> #include <iostream> #include <cmath> #include <cstring> #include <algorithm> using namespace std; int n,m,cnt,ans,num; int di[555555]; char…

题意:给定 n,m,把 n 的所有因数转 m 进制,再把各都平方,求和. 析:按它的要求做就好,注意的是,是因数,不可能有重复的...比如4的因数只有一个2,还有就是输出10进制以上的,要用AB.. 但我用的是ab..又没读好题....活该WA了好几次. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #includ…
