【杭电5053】the Sum of Cube

暂且算简单题目吧，有点暴力-_-
用__int 64就行了

#include<stdio.h>int main(){    int n,k=0;    scanf("%d",&n);    while(n--){        int i,j;        __int64 sum=0,l;        scanf("%d %d",&i,&j);        for(l=i;l<=j;l++){            sum=sum+l*l*l;        }        printf("Case #%d: %I64d\n",++k,sum);    }    return 0;}
