I like it!

this one was harder for sure

You should call it product (the result of multiplication), instead of sum (the result of summation/addition).

Jeeez, Nice n Clean

Yeah I get the same error too :(

ones you go from -1 to 1 of userrank ,progress will be 10 not 20 (According to question)

[JavaScript] example tests are not implemented at all.

Hi, Python translation is ready to be reviewed and approved: https://www.codewars.com/kumite/63c2e0017a10c31859770d49?sel=63c2e0017a10c31859770d49

This 5kyu kata is harder version of 4kyu kata?:)

Spend three days solving this, had learned a lot about pow modulo arithmetics and PF, but was not able to find solution - 2300+ passed tests but timed out. Anyway this is really not same 3kyu as similar pow modulo katas e.g. https://www.codewars.com/kata/5518a860a73e708c0a000027. This kata needs a lot more knowledge in number theory than other similar katas.

Please provide language (JavaScript?) and your code, cause it is difficult to give you any advice without info. Maybe you should check edge cases - empty string?

Hi. PLease review and approve C translation. https://www.codewars.com/kumite/639a132686b6980016a6f64c?sel=639a132686b6980016a6f64c
