Hashing functions return a wide range of integers. In order to transform these values into useful indices for our array we need a compression function. A compression function uses modular arithmetic to calculate an array index for a hash map when given a hash code.

### Instructions

**1.**

Create a `.compressor()`

method for your hash map.

It should take two parameters: `self`

and `hash_code`

.

**2.**

Take the modulus of the hash code by the map’s `array_size`

in order to reduce the hash code to a possible index for the array.

Return the modulus.
