I want to be able to search a 2d array, but want to do it recursively and using some sort of backtracking algorithm...
I have an array: arr
I want go through the entire array (it will have a user defined fixed length), and find out which slots are empty and which are not...
Please try and keep the code simple and comment it. Ive looked at examples here and couldn't understand them thoroughly...
