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.

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

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

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