The way the results are displayed makes it challenging to troubleshoot your query. I agree with Voila that it would be better to have the traditional SQL test assertion data display. Thanks and all the best!

Thank you for the prompt response - the error was in my query not in tests!

Hi! I clearly mentioned it in the description, "Ensure the age ranges include the entire span (e.g., up to but not including 21 years for the 18-20 bracket)." And the test that you mentioned checks exactly it: that person who is 40.5 would be a part of -40 bracket

Hi!
I believe that there might be an error in the 'Edge Test Case'. The only employee present in that data set is above 40 (born Aug. 2/1983) but the solution seems to require the employee to be between 26 and 40. Could you please look into this?

Not a kata issue ! The first solution does not pass because it returns the largest number in the array regardless of the sorting criteria. The second solution is correct and passes all the time.

i don't think regexp should be 8kyu

Read the description again.

I can see that there is a negative opinions about this approach but I am still quite new and still learning so I could someone please explain how this approach even works? I'm not really able to see the connection between how i's reversed order matching the reversed order of n produces the right result...

Thank you in advance for your time and help!

Same issue in Ruby...

Interesting but for me it was quite difficult and I think it's closer to a 5kyu or 6kyu.

Nice one but in my opinion it should be 8ky...
