Yo nutcrackers, good luck jacking.
If you want to earn that $€, you'll figure this out. It IS a very good kata with all the test examples and DESCRIPTION, it's perfect.
So stop whining and put your brains to work.

Doable, but a tough one. More like 6 kyu.

Keep up the Go learning!

Beautiful, because of such tasks I started enjoying programming.

Stop whining, all good here.
Understanding complex text comes along side with programming. Business people don't talk programming :)
Besides logic for the solution is implementable in excel...

Very nice kata, maybe a bit on the tougher end for 7kyu, nonetheless doable.
AND the explanation has it all. Read my fellow lambo drivers, read....

Extremely satisfying kata for this level, have fun!

It is totally doable for 7 lvl. Very little to do with coding skill, rather logic.

That was in it's own way extremely satisfying :), good kata for 7kyu

That's probably the hardest 7kyu kata that i've solved. In golang the whole channels topic was new, and since it was unclear what was meant to be returned it took longer than expected.

For all the whiners, yes it's a bit challenging, but over all it does fit 7kyu lvl, so keep your mind sharp and attention to details even sharper.
It's easier than some of the 7kyu katas' i've seen. All good, and may the force be with you.

I've seen worse. Besides test cases are there, so you could derive from those.

This should be upvoted! Comment section more than often hints toward the solution.

I was pleasantly fucked in the brain, after I saw the answers :D
