#include <bits/stdc++.h>
using namespace std;
int T, n;
void Main() {
cin >> n;
for(int i = 1; i < n; i++) {
int x, y; cin >> x >> y;
}
cout << ((n & 1) ? "Alice" : "Bob") << '\n';
}
int main() {
#ifdef zqj
freopen("1.in","r",stdin);
#endif
ios :: sync_with_stdio(0), cin.tie(0);
cin >> T;
while(T--) Main();
return 0;
}
这程序好像有点Bug，我给组数据试试？
