处理好像没问题 只是计算方法顺序不一样 为什么过不了

#include <bits/stdc++.h>
using namespace std;
#define int long long
int n,m,a[3005],q[3005],ans = 101;
signed main(){
	cin >> n >> m;
	q[0] = 0;
	for(int i = 1;i <= n; i++){
		cin >> a[i];
		q[i] = a[i]+q[i-1];
	}
	for(int i = m;i <= n; i++)
		ans = min(ans,q[i]-q[i-m]);
	cout << ans;
	return 0;
}
