#include<bits/stdc++.h>
#define rep(i,a,b) for(int i=(a);i<=(b);++i)
#define per(i,a,b) for(int i=(a);i>=(b);--i)
using namespace std;
using LL=long long;
int main(){
#ifdef xay5421
freopen("a.in","r",stdin);
#endif
int T;
cin>>T;
while(T--){
int n;
scanf("%d",&n);
for(int i=1;i<n;i++) scanf("%*d%*d");
if(n&1) printf("Alice\n");
else printf("Bob\n");
}
return 0;
}
这程序好像有点Bug，我给组数据试试？
