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

This kata require more details description, an example from start to finish perhapse.

IMHO it shouln't be kyu 7 kata, in comparison to other kyu 7 this is simply hard

Thanks, fixed :)

In the sample tests, sample 3 and sample 4 are identical. Might want to fix that.

Thank you for your feedback. 👍

I was trying about half a hour without result, but then suddenly remembered about <solution_name>, good kata, thanks :)

Well, I tried, it does works properly, what's the problem? :)

It doesn't work with non-ASCI strings.
Try this:

Expect(IsPalindrome("топот")).To(Equal(true))

It doesn't work with non-ASCI strings.
Try this:

Expect(IsPalindrome("топот")).To(Equal(true))

o_O

Yeah, I don't know why I didn't do it this way from the beginning. I fixed the kata, thanks

Indeed, I didn't noticed that initial code isn't mine, thanks

Why

Also you should process exception when there's no N-1 common letters "AbCD Abcd aBCd abcD" -> [""]

Expect(MinQuine("AbCD Abcd aBCd abcD")).To(Equal([]string{""}))

instead of just

Expect(MinQuine("AbCD Abcd aBCd abcD")).To(Equal([]string{}))

It's inconsistent to other results where all slots are strings of length N-1.

The current initial solution is the default one

package kata

func TwoOldestAges(ages []int) [2]int {
  return [2]int{"", ""}
}

You have to modify the signature to fit your tests, where MinQuine is expected.
