Solution for encoding and decoding unary messages using Chuck Noris' method.

UnaryMessages

A solution for generating unary messages using Chuck Norris' method, implemented in Elixir. Resulting encoded message contains only zeros and spaces. The processing pipe is as follows:

• convert characters to binary representations (7-bit aligned)
• join the binaries
• encode the leading sequence for each block of ones and zeros
  • "1" becomes "0 ", so the block of "111" becomes "0 000"
  • "0" becomes "00 ", so the block of "000" becomes "00 000"

Example:

Run iex -S mix (or iex.bat -S mix on Windows) in the project folder.

iex(1)> UnaryMessages.send("Hi")
"0 0 00 00 0 0 00 000 0 00 00 0 0 0 00 00 0 0"
iex(2)> UnaryMessages.receive("0 0 00 00 0 0 00 000 0 00 00 0 0 0 00 00 0 0")
"Hi"

Tests:

Test cases are included. Run mix test in the project folder.
