为什么我的代码一直会提交后显示 Wrong Answer.wrong output format Unexpected end of file - token expected。求助万能的大佬帮忙解答和改正。

我写的 SPJ 代码如下：

#include "testlib.h"
#include<bits/stdc++.h>
using namespace std;
int n , m , k , x , y , t;
char c;
string s;
bool a[3005][3005] , answer[3005][3005] , row[3005] , column[3005];
int main(int argc, char *argv[])
{
    registerTestlibCmd(argc, argv);
    n = inf.readInt();
    m = inf.readInt();
    k = inf.readInt();
    t = 0;
    memset(row , 0 , sizeof(row));
    memset(column , 0 , sizeof(column));
    memset(a , 0 , sizeof(a));
    memset(answer , 0 , sizeof(answer));
    cout << n << ' ' << m <<endl;
    for(int i = 1 ; i <= n ; i++)
    {
    	for(int j = 1 ; j <= m ; j++)
    	{
    		c = ans.readChar();
    		while(c == '\n')
    		{
    			c = ans.readChar();
			}
			a[i][j] |= c - '0';
			row[i] |= a[i][j];
			column[j] |= a[i][j];
		}
	}
	while(1)
	{
		if(t > 20000)
		{
			quitf(_wa , "You can only ask 20000 questions!");
			return 0;
		}
		s = ouf.readToken();
		if(s == "number")
		{
			cout << k << endl;
		}
		else if(s == "row")
		{
			x = ouf.readInt();
			if(x <= 0 || x >= n)
			{
				quitf(_wa , "%d is not in the range of [1 , %d]." , x , n);
				return 0;
			}
			if(row[x])
			{
				cout << 'T' << endl;
			}
			else
			{
				cout << 'F' << endl;
			}
		}
		else if(s == "column")
		{
			x = ouf.readInt();
			if(x <= 0 || x >= m)
			{
				quitf(_wa , "%d is not in the range of [1 , %d]." , x , m);
				return 0;

				return 0;
			}
			if(y <= 0 || y >= m)
			{
				quitf(_wa , "%d is not in the range of [1 , %d]." , y , m);
				return 0;
			}
			if(a[x][y])
			{
				cout << 'T' << endl;

			else

			}
		}
		else if(s == "answer")
		{
			cin >> x;
			if(x != k)
			{
				quitf(_wa , "Except %d seats, but found %d seats." , k , x);
				return 0;
			}
			break;
		}
		else
		{
			quitf(_wa , "Unknown command.");
			return 0;
		}
		t++;
	}
	for(int i = 1 ; i <= k ; i++)
	{
		x = ouf.readInt();
		y = ouf.readInt();
		if(answer[x][y])
		{

			return 0;
		}
		answer[x][y] = 1;
		if(!a[x][y])

			return 0;
		}
	}
	quitf(_ok , "Good job!");
    return 0;
}
