Bedtime Reading I--水题

分析：不断取余，满足条件的就加上

Code：

#include <cstdio>#include <cstring>#include <algorithm>using namespace std; int main() {    int n;    while(~scanf("%d", &n)) {        int sum = 0;        for(int i = 1; i <= n; i++)            if(n%i == 0)  sum += i;        printf("%d\n", sum);             }         return 0;}
