I believe random tests in Ruby and Coffeescript are corrupted

DO random tests still work in Coffeescript?

In this fork I tried to improve on the only two areas that may have been a bit questionable... That said the quality of @theropodMusings's translation is quite good.

• On the shuffle function there was no need to create temporary tables, and so I improved it a little bit.
• There was a mutation while the table was trying to be iterated, and while Lua's reference manual says it's safe «The behavior of next is undefined if, during the traversal, you assign any value to a non-existent field in the table. You may however modify existing fields. In particular, you may clear existing fields.», I don't think it's a good idea to rely on that behavior, specially when there's no need to.

Python 3.8 should be enabled.

The description says Somehow, I knew the third triangle had its first side unmarked, rather than its second, I'll have to take that into account were I to do this right., but without any diagrams or specification, this doesn't provide enough information to solve it. "First side" and "second side" don't have standard meanings. It's certainly not sorted by length, because in one of your examples, a>b. So even though I guessed correctly that 'c' is always the hypotenuse, it would be a bit fairer to tell us this in advance.

Can't change the test cases anymore, so it can't be fixed.

It should be pointed out that it's only more performant across multiple executions within the same memory space. If all you care about is the runtime of one execution, then pyramidka's is almost twice as fast, even when x is 1.

>>> factorial.lookup = []
>>> f1(1)
5.00679016113e-06
>>> f2(1)
9.05990600586e-06

>>> factorial.lookup = []
>>> f1(15000)
0.0543911457062
>>> f2(15000)
0.101855039597```

One random issue appeared too

Approved ;-)

Nice kata, biggest challenge for me so far :) Thanks!

A wild Python appeared!

Noted, nice kata btw.
