# 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".
```text
1 = wink
10 = double blink
100 = close your eyes
1000 = 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 input 3, the function would return the array
["wink", "double blink"] because 3 is 11 in binary.
Given the input 19, the function would return the array
["double blink", "wink"] because 19 is 10011 in binary.
Notice that the addition of 16 (10000 in binary)
has caused the array to be reversed.
