试试这个我写的SJ，再看看我的输出。

#include <iostream>
#include <algorithm>
#include <fstream>
#include <cstdlib>
using namespace std;

const char* msgNo1 = "Invalid Number";

int mat[6][6] = {0}, deg[6] = {0};
int ans;
bool mark[6] = {0};

void travel(int v0)
{
	mark[v0] = true;
	for(int i = 0; i < 6; ++i)
		if(!mark[i] && mat[v0][i])
			travel(i);
}

ifstream fout;

void err(const char* msg)
{
	cout << "Wrong Answer: " << msg << endl;
	fout.close();
	exit(0);
}

int main(int argc, char* argv[])
{
	if(argc != 4)
	{
		cout << endl << "Usage: check infile outfile ansfile" << endl << endl;
		return 0;
	}
	int i, j, k;
	
	ifstream fans(argv[3]);
	fans >> ans;
	fans.close();
	ifstream fin(argv[1]);
	for(fin >> k; k--;)

	fout.open(argv[2]);
	if(!(fout >> k)) err(msgNo1);
