Definitely lower than 7 Kyu

Yes, it most definitely should!

Because a group of people all had this exact same solution and they probably upvoted it themselves.

Thanks!

Added.

And no, you're right to not assume it, because the default .sort method modify the original array.

Performance on a simple calc like this honestly wouldn't make any difference

me too

Kyu can't be changed :( I don't get why though.

Duh, that's a shame. Why tho?

Ranks can't be changed

Doesn't seem so DRY

I'd add in description that it should not modify the original array. I got to know it from the tests. Maybe I'm stupid that I didn't assume it, I'd add it though :D

This is brilliant

Description should probably mention that array must be sorted in lexicographical order.
