Lua translation!

I think more fixed tests are needed. For example, test with capital letters

Java translation ready ! Review it!

Try to do this using slices and avoid converting the string to a list.

In Python, you can slice a string in reverse, but not in JavaScript. Maybe the description should be revised?

Ruby's tests are wrong, they don't handle spaces correctly. For example:
with

t45ba^^]qL2yNe5 Ea1m7IP:T4DEbSy KFT m:=SX_wgjQFgd_ mXuzlvKNg473l 

Tests expect "pln". However it's obvious that the third and fourth blocks, KFT and m:=SX_wgjQFgd_, contain no number, so the result should be 'pl n' (with two spaces that markdown does not display properly; that's also what my Python's passed code returns).

Ruby 3.0 should be enabled, read this to learn how to do it

Please organize the structure of test fixture as following (although it has been mentioned in the attached link, I'm repeated here again)

describe "<This message should describe the categories of test groups inside this block>" do
  it "<A short message describing this test group>" do
    expect(...).to eq(...) #Assertions
    #Or Test.assert_equals(user_response, reference_response)
  end
end
