Consider the following number system. Calculate the prime factorization for each number n, then represent the prime factors in a vector like so:

13 11 7 5 3 2

---------------

2: 1

3: 1 0

4: 2

5: 1 0 0

6: 1 1

12: 1 2

14: 1 0 0 1

18: 2 1

26: 1 0 0 0 0 1

60: 1 1 2

Each "place" in the number system represents a prime number. Given n, return the vector p.

As shown above, if n = 26, then p = [1 0 0 0 0 1].

The input n is always an integer greater than 1. Suppress any leading zeros. The length of the vector is determined by the largest prime factor.
