Not a kata suggestion

Ruby:

You are allowed to use a number more than once

(Actual & expected were flipped in the assertion, so your code actually failed to consider repeating elements)

Runs in Node v10.x ...for some reason

hey, thanks for the review, i modified the literals so that they are Integers; the random tests should now expect true ~50% of the time.

this kata makes no sense for floating point numbers and the tedious input validation mentioned in the description is against the authoring guidelines, and will have to be removed from all languages at some point (plus the kata has already been translated to statically typed languages where this kind of input validation is impossible)

1. Enabled Ruby 3.0 + RSpec [1]

2. Generate true cases more often

3. Added an edge cases [2]

4. Flipped actual & expected in the assertion [3]

The n generated in random tests are always a float, so returning false will pass all random tests. (This is because 1e5 & 1e9 are treated as floats in Ruby)

You can replace 1e5 with 10**5 to generate true cases sometimes. (False cases can be a mix of integers & float value, or purely integers, depends on you)

2. Refsol now recurses properly instead of calling user solution
