Yes, you scored 2 honor points for solving an 8 or 7 kyu challenge and an additional 30 honor points for advancing your overall rank to 6 kyu.

Your score is displayed nex you your Kyu - on the top right corner.

To see how much score I got for the challenge, I just calculate. The score I got after solving the challenge minus the last score I had. :)

Hi. How do you view the points scored?

Thank you. That explains everything.

That's normal. You got 30 points for reaching 6 kyu.

You can see the table of honor points here.

I solved 7 kyu kata and my points went from 92 to 124!!! From 7th kyu, I levelled up to 6th kyu. Is it normal?

I'm surprised this code has passed all tests. It doesn't validate the input. What if n is a string?

Maybe n is a number but not an integer?

What's the elif for?

It’s guaranteed that array contains more than 3 numbers.

and what happens when the unique is the first one?

Quick suggestion. Perhaps it would be better to say "All POSITIONS in the string should be retained." instead of "All spaces in the string should be retained."
Beginner might think spaces between strings or characters.

omg, I made very silly mistake. Thank you!

You don't return anything.
