Write a function called 'GetCombos' which has two parameters:
1st Parameter = A modifiable string (max length = 63 characters)
2nd Parameter = A callback function to be invoked for each combination
Constraints:
(1) If the string supplied to GetCombos is invalid, empty or too long then do nothing (just return immediately without invoking the callback function)
(2) If the callback function supplied to GetCombos is invalid then do nothing (just return immediately without invoking the callback function)
(3) Don't invoke the callback function with an invalid or empty string
(4) The output may be sorted or unsorted -- the order doesn't matter
(5) The output must not contain duplicates
