I am getting wa with my code. Can anyone help me what is wrong with my code?
Here is my code..

#include<iostream>

using namespace std;

int main (void)
{
int t,check = 1;

char in[100][101];

int m,n,i,j,k,l,q,e;

int r1,c1,r2,c2,t1,t2,t3,t4;

char c;

int count = 3 ;

int lin[20][2] ;

int inc = 1 ;

cin >> t ;

while(t)
{
cin >> m >> n >> q;

c = getchar() ;

for( i = 0 ; i < m ; i++ )
{
gets( in ) ;

}

for( j = 0 ; j < q ; j++ )
{
cin >> k >> l;

lin[j][0] = k;

lin[j][1] = l;

}

cout << m << " " << n << " " << q << "\n";

for( k = 0 ; k < q ; k++ )
{
i = lin[k][0] ;

j = lin[k][1] ;

r2 = i - 1 ;

c2 = j + 1;

t4 = c2 ;

r1 = i + 1;

c1 = j - 1 ;

t3 = c1 ;

c = in[j] ;

while( check )
{
// check from lower corner character

for( e = 0 ; e < count ; e++ )
{
if( in[r1][c1] != c )
{

check = 0;

break ;
}

c1++ ;

}

c1 = t3 ;

t1 = r1 ;

for( e = 0 ; e < count ; e++ )
{
if( in[r1][c1] != c )
{

check = 0;

break ;
}

r1 -- ;

}

for( e = 0 ; e < count - 1 ; e++)
{
if( in[r2][c2] != c )
{
check = 0;

break;

}

c2--;

}

c2 = t4 ;

t2 = r2 ;

for( e = 0 ; e < count - 1 ; e++)
{
if( in[r2][c2] != c )
{
check = 0;

break;

}

r2++;

}

if ( check == 1)

inc += 2 ;

r1 = t1 + 1;

t3-- ;

c1 = t3 ;

if( (r1 >= m) || ( c1 < 0 ) )

check = 0 ;

r2 = t2 - 1 ;

t4 ++;

c2 = t4 ;
if( (r2 < 0) || ( c2 >= n ) )

check = 0 ;

count += 2 ;

}

check = 1 ;

count = 3 ;

cout << inc <<"\n";

inc = 1 ;

}

t -- ;
}

return 0;
}

But still wrong ans.

After passing all the input found here in board,I was getting WA repeatedly..By working more on my algorithm I found my code breaks for following inputs..After fixing it I got Acc...

Hope this may help people getting WA..

I have tried all the test cases and still got a WA...

Code: Select all

#include <iostream>
#include <cstdio>
#include <cstring>

using namespace std;

int main(){
	freopen("output.txt","w",stdout);
	int m,n,q,value[101][101],a,b,temp,cc;
	char s[101][101];
	scanf("%d", &cc);
	while(cc>0){
		scanf("%d %d %d", &n, &m, &q);
		memset(value,0,sizeof(value));
		for(int i=0;i<n;i++)
			scanf("%s", &s[i]);
		value[1][1]=1;
		for(int i=1;i<n+1;i++)
			for(int j=1;j<m+1;j++)
				if(i==1||j==1)
					value[i][j]=1;
				else if(s[i-1][j-1]==s[i-2][j-2]&&s[i-1][j-1]==s[i-2][j-1]&&s[i-2][j-2]==s[i-1][j-2])
					value[i][j]=min(value[i-1][j],min(value[i-1][j-1],value[i][j-1]))+1;
				else value[i][j]=1;
		printf("%d %d %d\n", n,m,q);
		for(int i=0;i<q;i++){
			temp=-1;
			scanf("%d %d", &a, &b);
			for(int j=1;j<value[a+1][b+1];j++)
				if((value[a+1+j-1][b+1+j-1]+1)!=value[a+1+j][b+1+j]){
					temp=j-1;
					break;
				}
			if(temp==-1)
				printf("%d",(value[a+1][b+1]-1)*2+1);
			else printf("%d", temp*2+1);
			if(!(cc==1&&i==q-1))
				printf("\n");
		}
		cc--;
	}
	return 0;
}

Can anyone tell me what's wrong or provide me with some test cases, please?

Thank you!

Print a newline at the end of the last line of the output.
