The behavior of the code in case of exceptions is completely not described. The task is a puzzle. And a waste of time.

It's unclear what the goal is -- performance? type checking? -- my solution passed before I even started to address either

or just input Words. why do input validation when you have a frigging type system to do it for you?

python new test framework + random tests

I cannot wait to solve more complex problems on dynamic programming and efficient algorithms just like this one, thanks for the kata.

Great mathematical coding challenge to have fun with.

Approved

python new test framework + random tests + snake_case (with backward compatibility) are required. updated in this fork

Prolog translation

Closed (Kumite approved)

Fixed by fork above.

Approved.

Kumite with a fix

Ruby fix (use Ruby 3.0 with new test framework + random tests)

JavaScript fix (move to mocha+chai, add missing random tests)
