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

• 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)

• 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)

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