Fun kata, i think "proper spacing" should be clarified something like "space between* per word" for clearity. (Actually that was clarified i didn't read it awsome)

Got it, without the packages, it could be challenging, you're right.

This task is ranked 4 kyu because it is meant to be solved in languages without BigInteger support. It was initially created in JavaScript before BigInt was a thing. Unfortunately, the kata aged very bad and spoiled by the fact that it was translated to languages with big integers, or bigintegers have been added to existing languages.

It is still relevant for C, C++, and some old languages, and languages which still have no bigint numeric types, but there's not many of those today.

I updated the go translation and i would appreciate a review. Additionally, I believe it might too easy for a 4 kyu level.

You can always print the input at the beginning of your function to see what might be causing the issue.

That was fun, i completed with only one loop. I seem to be enjoying these type of questions more, apparently. :)

LGTM. Approved. Thanks!

Thank you for the response, sorry about that that's my first translation :)
I Removed comments and replace the placements.

Thanks for the translation...

I think you've put the "Sample Test Cases" and the "Test Cases" in the wrong files -- IMO should be the other way around.

Please also remove those TODO comments from your test files.
