Hash Maps: Python
Creating the Compression Function
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.
