My issue

When run on each test case individually, your code appears to be correct. However, when run on the entire test file, it returns a WA. The most common reasons for this are that you do not have a newline after each test case, or you do not reinitialize some variables in each test case.

My code

#include <bits/stdc++.h>
using namespace std;
#define ll long long
#define pb push_back
#define fast_io ios_base::sync_with_stdio(false);cin.tie(0);cout.tie(0);
#define fr(i,a,b) for (int i=a; i<b; i++) 
#define loop(x,n) for (int x=0; x<n; x++) 
#define mod 1000000007
#define inf (1LL<<60)
#define all(x) (x).begin(), (x).end()

const int N = 1e6+5;
bool isPrime[N];

void precal() {
    memset(isPrime,1,sizeof(isPrime));
    for (int i=2; i*i<=N; i++) {
        if (isPrime[i]) {
            for (int j=i*i; j<=N; j+=i) {
                isPrime[j] = false;
            }
        }
    }
}

void solve() {
    int n;
    cin>>n;
    if (n%2==1) cout<<1<<" ";
    n=n/2;
    for (int i=2; i<N; i++) {
        if (!isPrime[i]) continue;
        cout<<i<<" "<<i<<" ";
        n--;
        if (n==0) break;
    }
    cout<<endl;
}

int main() {
    fast_io;
    cout<<fixed;
    cout<<setprecision(10);
    precal();
    int t;
    cin>>t;
    loop(x,t) solve();

your code is failing for test case n=1;
