To those who are getting a WA on some hidden test case... My advice to you is to think of a test case when we have only 1 line and only 1 column and thus design your solution keeping that in mind. Also, a little tip try to use string or character arrays for the following lines and just print accordingly on the basis of the number of the line you are iterating on currently. Hope this helps. Cheers!

Can be done using while and for loop easily. Just check individual conditions.
