answer

#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?
