1e-6 now instead of 1e-9, is it ok?

Fixed.

Your solution passes all non performance tests now on submit.

You are right, the ref sol was 1 off in some edge case. In this example, it mistakenly thought it would make the view. Fixed

done

I found the bug in reference solution. I retested with each of the current submissions. Thanks for pointing this out.

yup, I definitely made a mistake

copy & paste

fixed

It's not a duplicate. The integers to be paired in that kata is arbitrary, so only brute-force is viable. This kata specifically pairs up integers from 1 to 2n, which admits different kinds of solutions.

My solution is of length 25, but don't shorten the character limit. I find that even 26 is slightly too strict for a 6 kyu kata.
