200A - Cinema — i was solving this problem which was in a20j ladder A(No.100) . And i solved it using brute force using this submission 173330360 . it worked for all testcases in my computer but on codeforces it went to an error of wrong answer. the input was totally same. i even tried an online compiler and that website gave me an even different answer than both of the previous answers. please help me. i know the solution is kinda messed up since i just started competitive programming but please i need help.

in line number 22 you wrote int hall[row][col] = {0}; well, this is wrong if you want to make your whole array equal to 0 you can do a for loop like this : 

for(int i = 0; i < row; i++)
    for(int j = 0; j < col; j++)
        hall[i][j] = 0;

if you do this your output will be correct.
