This code is not working with inputs like a7 and b 6. It works with corner adjacent just not edge adjacen. It is supposed to handle inputs that are in these formats: (5, 5), 3 0, 4,1, a7, b 2 andd also output the same format. It works for everything except a7 and b 2 format with the edge adjacent and not adjacent
