Abba Babba Binary Challenge

This challenge should take 10-15 minutes to complete.

Instructions:

Write a method that:

  • takes an integer as input
  • converts the number to binary
  • swaps any 1's for A's and swaps any 0's for B's and returns the output

Example: The binary representation of 12345 is 11000000111001 so your method should return AABBBBBBAAABBA
