#include<bits/stdc++.h>
using namespace std;
int read(){
int x=0;char ch=getchar();
while (!isdigit(ch)) ch=getchar();
while (isdigit(ch)) x=x*10+ch-48,ch=getchar();
return x;
}
void solve(){
int n=read();
for (int i=1;i<n;i++)
read(),read();
puts(n&1?"Alice":"Bob");
}
int main(){int T=read();while (T--) solve();return 0;}
这程序好像有点Bug，我给组数据试试？
