# Proof of Kaprekar's constant in Scheme, Python, and Elixir

I thoroughly enjoyed this delightful post on Kaprekar's constant, which was new to me. Similar to the post author, I also like to use programming to understand mathematical concepts. I thought it would be a fun exercise to translate the example Ruby code to my favorite language, Scheme, and two other languages that I'm learning, Python and Elixir.
