#include<bits/stdc++.h>
//#define int long long

signed main() {
    std::ios::sync_with_stdio(false);
    std::cin.tie(0);
    std::cout.tie(0);

    int T;std::cin >> T;
    while (T--)
    {
        int n;std::cin>>n;

        std::vector<int> a(n+1,0),cnt(n+1,0);
        for(int i = 1;i<=n;++i)std::cin>>a[i],cnt[a[i]]++;

        std::sort(cnt.begin(),cnt.end());

        int ans = 0;
        int x = cnt[n],y = cnt[n - 1],z = x & y;
        while(z - (z & -z) > 0)z -= (z & -z);
