I THINK IT SHOULD WORK FINE FOR(0,0),(1,0) OR (0,0) IF U JUST WRITE FOR EVERY HITS
B[ROW][COLUMN] = 0,
i.e,ROWS FIRST AND COLUMNS AFTER

The Rows Should Be Written Before The Columns,
Therefore The Code Should Be
If(row<=6 && Column>=2)
B[row+1][column-2] = 0;
Check...

I AM UNABLE TO UNDERSTAND WHAT UR PROBLEM IS BUT WHATEVER I COULD GATHER FROM THAT I COULD SAY THAT: U MUST CHECK BEFORE CALCULATING THE HITS THAT WHETHER BY SUBSTRACTING THE COLUMN BY 2 AND THE ROW...
