1. Enabled Ruby 3.0 [1]

2. Made the description language agnostic [2]

3. Simplified random tests

4. Fixed an error when checking the length Set.new(ary) != 1 --> ary.uniq.size != 1

Calling the ref sol from user solution still passes all the random tests

Moved inside describe block, tested from user solution and it gives undefined method 'solve' error

Fixed

Enabled Ruby 3.0 [1] & Made description language agnostic [2]

All done in this fork

Expected solution is affected by input mutation.

To resolve this, compute the expected solution first before running the user solution method.

Reference solution method is accessible from the user solution, change it to a Proc / ->(){} / lambda instead

New test framework already done in this fork

Parameter name fixed in this fork

1. snake_cased the param name [1]

2. Moved user function inside the it block [2]
