建议额外用个循环，减少写dfs的难度
```
void dfs(int ms,int ps,int start,int cnt,int m){
if(cnt == m){
minn = min(abs(ms - ps),minn);
return;
}
for(int i = start;i <= n;i++){
dfs(ms * a[i].x,ps + a[i].y,i + 1,cnt + 1,m);
}
}
int main(){
for(int i = 1;i <= n;i++){
dfs(1,0,1,0,i);
}

输入建议索引从1开始,数组开大一点

@[LYM20114](/user/531776) 好像按照这样写是可以的，不过，哥，能帮我改一下本身的吗，因为是套模板，现在还不熟，就不想改了
