哈哈哈

比起用while循环我觉得for循环更简单

#include<bits/stdc++.h>
using namespace std;
int main(){
    int x,y;
    cin>>x>>y;
    int sum = 0;
    for(int i = 1;i <= y;i++){
        if(x != 6 && x != 7){
          sum += 250;
        }
        if(x == 7){
           x = 1;
        }else{
           x++;
        }
    }
    cout<<sum;
    return 0;
}
