Secret Handshake

Instructions

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".

00001 = wink
00010 = double blink
00100 = close your eyes
01000 = jump


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

Given a decimal number, convert it to the appropriate sequence of events for a secret handshake.

Here's a couple of examples:

Given the decimal input 3, the function would return the array ["wink", "double blink"] because the decimal number 3 is 2+1 in powers of two and thus 11 in binary.

Let's now examine the input 19 which is 16+2+1 in powers of two and thus 10011 in binary. Recalling that the addition of 16 (10000 in binary) reverses an array and that we already know what array is returned given input 3, the array returned for input 19 is ["double blink", "wink"].
