Random test assertion message substitutes the wrong value: Should be equal to xxx has the input rather than the expected value.

Also, some parts of the random test input range do not make sense: at height like 218cm the "height needed to jump" becomes negative, when it really should be 0.

There are absolutely no information that can help deduce the formula, except a whole bunch of inputs and expected values generated by the random tests.

This is not a "puzzle", this is just blindly fitting data to get a formula. And not a good one at it either, if it is just a linear relationship.

This is just a trivial variant of https://www.codewars.com/kata/574c5075d27783851800169e.
