@jonny2345678 this is the best kata i've ever done in my life. And i do karate. idk what @FArekkusu is talking about - this is perfection! You should work for DeepMind I reckon.

Duplicate of the duplicate https://www.codewars.com/kata/617e01e7b328a500334bdde8, retired yesterday...

I have edited the test case code for your first comment about the it blocks, I hope this has solved this first issue

https://docs.codewars.com/authoring/guidelines/submission-tests/#input-mutation

Thanks for the tips, I'm new to this, can you briefly explain what you mean that users can modify the input? and how I can stop this?

• There's no benefit from having 100 it blocks all saying "Random Test Cases"
• The user can modify the input
• Trivial map/filter/reduce is not a novel kata idea (although increasing the number of conditions does somewhat make it less trivial, I don't think that throwing in a lot of 8-kyu subtasks will make this kata unique)

Thanks very much! still new to this :)

@jonnywong28: if you're interested in authoring kata, you should begin with reading the entire documentation about it.

Cheers

• Test framework and solution should be imported explcitly in the final tests
• Final tests are not using describe and it blocks
• No fixed tests
• Random tests compare the result with itself
• The user can modify the input - depends on the issue above
• "The returned list should be ordered alphabetically" - not tested - depends on the issue above
• Trivial map/filter/reduce is not a novel kata idea (although increasing the number of conditions does somewhat make it less trivial, I don't think that throwing in a lot of 8-kyu subtasks will make this kata unique)

This is a trivial map/filter/reduce kata. Unless you change the task significantly, no matter how many little conditions you add, it's still going to be a duplicate. Considering this kata has 25% approval rate after 10 votes, it's very likely to be retired soon anyway.

Thank you! Since the string must also begin with a letter from (a-m), isn't this unique? If not, I'll go away and change it again

Sorry but changing this to a multiple of 3 still makes this kata a duplicate of existing ones (filtering plus string manipulation).

Thank you! I have added random test cases now :)

I changed the question slightly anyway to try and avoid duplicating

Thanks for the feedback, I have made changes to sort out all of these issues, I hope it's better now
