O(N² + M²). This is bad practice, in fact.

this is more neat way of doing the same

Very smooth

Same as my solution. Didn't know you can jon two lists of strings. :)

Its a good answer

It doesn't modify the arrays, but creates a new array.

This is clever, but not so intuitive in my opinion.
But I'm just getting started with Python and programming in general, so I might change my opinion further down the rabbit hole!

Very elegant solution, thanks for the lesson!

Hello,
from what I understand, if (number % a > 0 or number % b > 0) it will return False because then that is some value.
number % a here is equals to number % a > 0.
so, the program returns True if number % a and number % b DO NOT have any values( because then they are of value 0 )

thanks for the comments
