da nice vibe

not a Kata issue (and the author is gone so i guess it's pointless to reply)

There are so many top programmers without college education who do just fine without math.

Pretty good challenge! ..Did sting a bit because I had to remove a long chunk code that I thought would speed the process up, but I learned a thing or two about code efficiency.

OP solved it, closing

not a suggestion ~~ you need to refactor your code for performance

Approved

Not a question, don't post solution in discourse

Not an issue.

You just have to know about substraction ;)

You can't go very far away in coding without knowing maths at least at college level.

Ruby 3.0 should be enabled, see 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

I think you're a genius.
