how much do you rank it

Raised as an issue.

Was my solution invalidated? It doesn't seem to count towards my honor points and rank...I did not cheat

Thanks! No problems now.

Don't mutate the input lists. I've made some changes to avoid this problem too.

How is this correct?

Testing for [2, 4, 0], [0, 0], and 2
It should work for random inputs too: 0 should equal 8

Also I passed all the fixed tests but failed all the random tests...

Julia tests give weird strings with empty lines for which the description does not provide clear indications. Those cases are not tested in other languages, or the expected results are different:

stripcomments("stripcomments(str, ms) = nomorecomments(please())\n# Julia comments!\nstripcomments(\"I hope it works\") # but I bet it won't\n", ["#"]) --> "stripcomments(str, ms) = nomorecomments(please())\nstripcomments(\"I hope it works\")"

Here my Python's solution would return 'stripcomments(str, ms) = nomorecomments(please())\n\nstripcomments("I hope it works")\n'.

Crystal tests are incorrect:

solution("pears pears apples\nbananas\nwatermelons oranges oranges pears watermelons\nwatermelons avocados ,  watermelons , ", ["@"])
Expected: "pears pears apples\nbananas\nwatermelons oranges oranges pears watermelons\nwatermelons avocados ,  watermelons , "
     got: "pears pears apples\nbananas\nwatermelons oranges oranges pears watermelons\nwatermelons avocados ,  watermelons ,"

Description states: Any whitespace at the end of the line should also be stripped out.

I think the reference solution doesn't strip the line if it doesn't contain the separator, but that's not in the description and it doesn't match with other versions. I'm not sure it's the only problem.

Not a 4 kyu, thanks for the easy points :)

Best kata I have ever done to date :)

No random tests...
