submission error

[_iojw]

I'm trying to submit code for UVa 469 - Wetlands of Florida. I'm fairly certain that my code outputs the correct answer however I get submission error whenever I submit it. The site spends a few minutes on Running then it becomes submission error. To my knowledge, submission error means that the problem isn't with my program but with the site. I recently changed my username if it matters, around a day ago. My new username is iojw (id 214488). Could anyone tell me what is wrong?

That seems to show up in some problems. It could be an issue with your code, maybe a TLE.

Everyone is getting submission error on this problem for the last 22 days.

problem: 469
why getting submission error?? please help

Code: Select all

#include<iostream>
#include<cstdio>
#include<cstring>
#include<stdlib.h>


using namespace std;

char cell[100][100];
int length[100],result[10010];
int color[100][100];
int r,s;

int get_len(int i,int j)
{

	if(i>r || j>=length[i] || i<0 || j<0) return 0;

	if(color[i][j]!=0) return 0;
	if(cell[i][j]=='L') return 0;

	color[i][j]=s;

	int count=1;

	count+=get_len(i-1,j-1);
	count+=get_len(i-1,j);
	count+=get_len(i-1,j+1);
	count+=get_len(i,j-1);
	count+=get_len(i,j+1);
	count+=get_len(i+1,j-1);
	count+=get_len(i+1,j);
	count+=get_len(i+1,j+1);

	return count;

}

int main()
{

memset(length,0,sizeof(length));
	int cases;
	bool blank=false;

	scanf("%d",&cases);
	getchar();
	getchar();
	while(cases--)
	{
		if(blank) printf("\n");
		else blank=true;
		memset(color,0,sizeof(color));

		int row=0;
		gets(cell[row]);

		while(cell[row][0]=='L' || cell[row][0]=='W')
		{
			length[row]=strlen(cell[row]);
			row++;
			gets(cell[row]);

		}
		r=row-1;

		while(strlen(cell[row])!=0)
		{
			bool flag=false;

Most probably there won't be any blank line after the last input (for the above problem 469), but my program is not ending without getting that blank line so can you please tell me that how can i decide that this is the last input and terminate my program???

gets returns NULL if EOF is reached.
