Thx a lot!!!

it's more interesting to read 9 lines instead of one, isn't it?

ranks cannot be changed

Good advice.Thanks.

Can you please explain it? I see it as great solution with bitwise left shift but honestly I do not get why it works.

Yeah, nice solution. That while is like big slap to creator what denied if, switch and ?: :D

Please note in description, that before final "big tests" stock should be always "reseted". Because with your constructor one time, it subtract and solver can riddle why - and that IMO should not be part of kata.

Nope. It is not only hard, but also used technology specifications. See https://docs.codewars.com/curation/references/kata-ranks/

Here is not imho • no pressure on utilizing, • no advantage design pattern - one while, one for loop and list ... •I do not think intricate business requirements, • also no advanced concepts.

4 kyu kata represent a competent programming level. At this level, the kata begin to take some serious thought to complete. They include tasks that may handle:

Computer science concepts utilizing complex algorithms
Advanced design patterns
Understanding intricate business requirements
Advanced concepts such as concurrency, parallelism, meta programming and cryptography

Wow...at first view it was "easy peasy" after while it was "ehmm...."

Woooo...great :D. I hope I would know that. I told to myself, no way this is 8 :D (see my solution)

That with Arthas and Lisa was very good. Was it intentional? @frkn2076

One of the "harder 7kyu"s

Sorry for readers. I have not know about ModPow in BI :D so this is completely from head and that step with "iDunnoWhyItWorks" I would like to explain from somebody who knows the answer :D

Hi, in description is (3, 3) -----> 1 (3^3 = 9)....is 3^3 really 9? :) .

Very nice. It is like chalk and cheese :). Great work (y)
