Hellloooooooooo !!
Here is a commit (at public/16863
) that also handles prime powers (not just primes) as the wikipedia source claims.
What it does:
- Change the doctests to test all new cases (also a bit faster than the previous doctest)
- rename
fact
tofactorization
- Add a reference toward wikipedia
- Use
[x**2 for x in SET]
to compute the list of squares.
Your turn !
