# Secret Handshake
|
|
|
|
> There are 10 types of people in the world: Those who understand

|

|
|
|
|
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.
|
|
```
|
|
|
|
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.
