本来想拿两分输出NO结果拿了90分，哪位大佬能帮我调一调

#include<bits/stdc++.h>
using namespace std;
#define int unsigned long long
const int N = 1e6 + 50;
int T, n, m, a[N], b[N];
bool mark[N];
void prime(double n)
{
    for(int i = 2; i <= n;i++)
    {
        if(mark[i] == 0)
        {
        	for(int j = 2; j * i <= n;j++)
        	{
        		mark[i * j] = 1;
			}
		}
    }
}
signed main()
{
	cin >> T;
	while(T--)
	{
		cin >> n >> m;
		for(int i = 1; i <= n;i++)
		{
			cin >> a[i];
		}
		for(int i = 1; i <= m;i++)
		{
			cin >> b[i];
		}
		cout << "NO" << '\n';
	}
	return 0;
}
