Secret Handshake

Write a program that will take a decimal number, and convert it to the appropriate sequence of events for a secret handshake.

There are 10 types of people in the world: Those who understand binary, and those who don't.

You and your fellow cohort of those in the "know" when it comes to binary decide to come up with a secret "handshake".

1 = wink
10 = double blink
100 = close your eyes
1000 = jump


10000 = Reverse the order of the operations in the secret handshake.

handshake = SecretHandshake.new 9
handshake.commands # => ["wink","jump"]

handshake = SecretHandshake.new "11001"
handshake.commands # => ["jump","wink"]

The program should consider strings specifying an invalid binary as the value 0.

To run the tests simply run the command go test in the exercise directory.

If the test suite contains benchmarks, you can run these with the -bench flag:

go test -bench .
