minn的初始值写小啦
```c++
#include<bits/stdc++.h>
using namespace std;
int q[10000],head=1,tail=1;
int a[3005];
int main()
{
int n,m;
cin>>n>>m;
for(int i=1;i<=n;i++)
{
cin>>a[i];
q[tail]=a[i];
tail++;
}
if(m==0)
{
cout<<'0';
return 0;
}
long long minn=1e18;/////////////////////////
for(int i=1;i<=tail-m+1;i++)
{
int x=0;
for(int j=head;j<head+m;j++)
{
x+=q[j];
}
if(x<minn)
{
minn=x;
}
head++;
}
cout<<minn;
return 0;
}
```
