My issue

There’s issue in submission

My code

#include <iostream>
using namespace std;

int main() {
	// your code goes here
	
    int T;
    cin>>T;
    
    
    int n,k;
    
    
    while(T--)
    {
        int A[n];
       int B[n];
        cin>>n;
        cin>>k;
        for(int i=0;i<n;i++){
            cin>>A[i];
            cin>>B[i];
        }
        
    for(int i=0;i<n;i++)
    {
        
        if(A[i]+B[i]>=k)
        {
            cout<<"YES";
        }
        else
        {
            cout<<"No";
        }
    }
        
    }
	return 0;
}

@mitaoe723
your logic is not right.
plzz refer the following solution for better understanding of the logic.

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

int main() {
    int t;
    cin >> t;

    while (t--) {
        int n, k;
        cin >> n >> k;
        vector<int> a(n);
        vector<int> b(n);

        for (int i = 0; i < n; i++) {
            cin >> a[i];
        }
        for (int i = 0; i < n; i++) {
            cin >> b[i];
        }

        sort(a.begin(), a.end());  // Sort array A in ascending order
        sort(b.rbegin(), b.rend());  // Sort array B in descending order

        bool possible = true;  // Assume it's possible unless proven otherwise

        for (int i = 0; i < n; i++) {
            if (a[i] + b[i] < k) {
                possible = false;
                break;  // No need to continue checking once the condition is not met
            }
        }

        if (possible) {
            cout << "YES" << endl;
        } else {
            cout << "NO" << endl;
        }
    }
    return 0;
}
