二分匹配代码略..

int main(){
	
	//while(scanf("%d%d",&u,&v)){
	while(cin>>u>>v){
		int k,t;
		int i=0;
		memset(c,false,sizeof(c));
		while(i<u){
			//scanf("%d",&k);
			cin>>k;
			while(k-->0){
				//scanf("%d",&t);
				cin>>t;
				c[i][t-1]=true;
			}
			i++;
		}
		//printf("%d\n",Match());
		cout<<Match()<<endl;
	}
	return 1;
}

• 应该这样写吧，while( scanf("%d%d",&u,&v) != EOF ) (0) Gchris 2007-12-13 09:04:15
