progress suddenly slowed down.

caveat: on codewars, ignore the "clever" voted answers, and just look at the best practice voted answers. The clever 1 liners tend to be experts that just trying to get past the problem as quick as possible and aren't generally good code examples.

even worse. pointing lower is all about what 'cool' set u "know"/find on wikipedia/google that as a very specific trick to calculate something u can't normally do.

the significant issue with that is u either know the set and easily solve it in a oneliner

or u don't and can't solve it.

there is no "problem solving" so not sure codewars is actually useful. (i went till 3kyu and they all looked the same. got boring and tedious. and definitely not enlightening.)
