Kata

In this Kata you will get a non-negative integer - num. Your goal is to factorize the number - which means decompose it to the product of other numbers. You should get to the smallest possible multipliers - the prime numbers - that produce num. For the purpose of this Kata, assume that factorization of '0' returns 0, and of '1' returns 1.

• consider the running time of your code

For example:

4*3
> 12

factorize(12)
> [2,2,3]

factorize(1)
> 1
