This is too easy for 5 kyu, solved it in 3 minutes

In python, this error started appearing randomly:

Traceback (most recent call last):
File "main.py", line 3, in
Test.assert_equals(sorted(two_sum([1,2,3], 4)), [0,2])
TypeError: 'NoneType' object is not iterable

I don't think it's from my code, it's from the sample tests.

Brilliance

this is what I probably would've done

I don't know how slicing works

just.. wow
