answer

#include <bits/stdc++.h>
using namespace std;

#define FOR(i, a, b) for(int i = (a); i < (b); i++)
#define RFOR(i, a, b) for(int i = (a) - 1; i >= (b); i--)
#define SZ(a) int(a.size())
#define ALL(a) a.begin(), a.end()
#define PB push_back
#define MP make_pair
#define F first
#define S second

typedef long long LL;
typedef vector<int> VI;
typedef pair<int, int> PII;
typedef double db;

void solve()
{
	int n;
	cin >> n;
	FOR (i, 0, n - 1)
	{
		int a, b;
		cin >> a >> b;
	}
	cout << ((n & 1) ? "Alice" : "Bob") << '\n';
}

int main()
{
	ios::sync_with_stdio(0);
	cin.tie(0);
	
	int t;
	cin >> t;
	while (t--)
		solve();
	
	return 0;
}

这程序好像有点Bug,我给组数据试试?
