Problem 42830. Hilbert numbers

Given a positive integer, n, return h as follows:

1. If n is not a Hilbert number, return h = 0

2. If n is a Hilbert prime, return h = 1

3. If n is a Hilbert non-prime, return all of its Hilbert factors in one sorted vector.

Example 1:

n = 3

h = 0

Example 2:

n = 5

h = 1

Example 3:

n = 45

h = [5 9]

Example 4:

n = 441

h = [9 21 49]
