算了我来帮你吧：
```c
#include<stdio.h>
struct week {
int num;
struct week next;
}day[7];
int main() {
int i,x,n,weekend=0,s;
struct week p=&day[x-1];
for(i=0;i<7;i++) { if(i==6){
day[i].next=&day[0];
day[i].num=7;break;
}
day[i].next=&day[i+1]; day[i].num=i+1;
}
scanf("%d %d",&x,&n); for(i=1;i<=n;i++) {
if(p->num==6||p->num==7)
weekend++;
p=p->next;
}
s=(n-weekend)*250;
printf("%d\n",s);
return 0;
}
```
