Retired.

This kata is a subject to deduplication process here: https://github.com/codewars/content-issues/issues/122.
Please join the discussion to help us identify duplicate kata and retire them.

You can process all 12,000 in under a second. So the test cases should simply be a lookup rather than generating the solution for each random test. This would let you increase the random tests to say 500 or so.

Python, Ruby (possibly others):

• solver function is very inefficient: all possible results can be precalculated in about 1s, instead of being calculated on-the-fly; and thus there are only 50 random tests (for a 4kyu kata)

Yes, unfortunately I wasn't aware of that kata as discussed below

Is this really different from GiacomoSorbi's Compare Powers? Maybe if you made the numbers significantly bigger, but right now my super naive solution from when I'd only started coding passes... and Compare Powers is already in Ruby/JS/Python and four other languages.

Making duplicate katas is not against the rules, but at the same time is not welcome (if B4B wasn't so quick, your kata wouldn't get approved at all). You shouldn't worry much about it, unless you can't live with the fact that your kata is not totally unique :P
