#include using namespace std; int main() { long long bigNum,i,cnt,ans; while(cin>>bigNum&&bigNum) { cnt = 0; ans = bigNum; while(bigNum != 1) {

质因数分解。#include #include #include using namespace std; int isPrime[432],pChart[432]; long long cntC[432][432]; int cot; void getPrime() { memset(pChart,0,sizeof(pChart)); int i,j; for(i

一看这个大数据就知道是数学题啦~~ 发现规律就可以啦~ import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); long s,t,cnt,sum,i,cas = 0,n; n = in.n
