    Same for me :/ someone please help

    int main() { int n,k,q,r=0; cin >>n>>k>>q;

    int b[n];
int m[q];
for (int i=0;i<n;i++)
   {
    cin >> b[i];
   }
for (int i=0;i<q;i++)
    {
     cin >> m[i];
    }
for (int i=0;i<k;i++)
    {
        r=b[n-1];
    for(int j=n-1;j>0;j--)
        {
          b[j]=b[j-1];
        }
        b[0]=r;
    }
 for(int i=0;i<q;i++)
   {
       cout << b[m[i]]<<endl;
   }
return 0;

    }
