只A１，２，３点，码风有点清奇离谱，不知道哪里少讨论了

#include<bits/stdc++.h>
using namespace std;
int t,a[10001],b[10001],c[10001];
int ans[10001];
int main(){
	scanf("%d",&t);
	for(int i=0;i<t;i++){
		scanf("%d%d%d",&a[i],&b[i],&c[i]);
		if(a[i]==0&&b[i]==0)ans[i]=0;
		else if(a[i]==0||b[i]==0||c[i]==0){
			if((c[i]==0&&a[i]==b[i])||(a[i]==0&&b[i]==c[i])||(b[i]==0&&a[i]==c[i]))ans[i]=1;
			if((c[i]==0&&a[i]!=b[i])||(a[i]==0&&b[i]!=c[i])||(b[i]==0&&a[i]!=c[i]))ans[i]=2;

		}
	}
	for(int i=0;i<t;i++){
		cout<<ans[i]<<endl;
	}
	return 0;
}
