Rate
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.
