Start from 1 side and only one direction.
Lets say you start from right to left, process 1 character and recursively call for the unprocessed string.
At the same time, check the last 2 chars, if they are less than 26, recursively make another call for the two digit number and pass the remaining string.
Base condition till the list is empty and print
