Something is broken on the third test case. I think the blank line between the 2nd and 3rd line of text is what's messing it up.
I submitted a solution that works for the first two cases and outputs perfect result (including the index output) for the last case on my desktop.

Somebody at the Cody team should check their test cases.

There is a workaround for the broken 3rd test case:
Because of the empty line, the size of sl is 2x2 instead of 1x4. So to bring sl into proper shape, just do str_list = str_list(:)' at the beginning of your code. This will leave the input for the first two test cases unchanged.

Thank you Jan for the workaround for the third test case.

Test suite doesn't check whether str_index_list is correct or not. It's incomplete.

Simon Thomas on 19 Sep 2019

There seems to be no check on the word indexing part of the problem. I passed the test suite without indexing at all.

Stephan Allgeier on 17 Dec 2019

If non-vector input lists are valid inputs (test case 3), this should be stated explicitly in the problem description

Rafael S.T. Vieira on 12 Jun 2020

I know people are complaining about indexes, but the problem did not state how indexes should be created. And if there is no requirement, anything can be true.

Li Kehan Li on 17 Jun 2020

tough for me to create the right index.

Drake Madison on 19 Aug 2020

Problem has been broken for YEARS!!!! Needs to be fixed or removed!!!! word index lists are never even checked. Third test case has a bug in input.

the third test case may be broken, I can find no difference between my output and the output listed, and on my matlab the assertion does not fail.

The test suite doesn't even test half of what the problem asks for,

This solution properly solves for the string_index_list output, though this is not checked in the test suite.

Obviously, the index list is not checked...

The test suite does not check the 2nd output argument. This solution is not correct.

I forgot to do the str_index_lst, but the evaluator still accepted this. This should really be rejected as a solution.
