The test function has some incorrect values: Nebraska and Nevada are incorrectly removed, Rhode Island, South Carolina, South Dakota and West Virginia are incorrectly left in.

Ned Gulley on 26 Jan 2012

I've fixed the problem and you're now the leader. Sorry about that!

Richard Zapor on 3 Jun 2012

A second test case is needed for this problem. 'New York Nevada' should suffice.

Ned Gulley on 5 Jun 2012

I added another test, similar to the one suggested. Thanks for the comment Richard!

I keep getting 'inappropriate content' errors.

"Remove inappropriate content" error...

What is " two_word name"??

Sanzhar Askaruly on 11 Aug 2019

if i would grasp all regexp possibilities in depth.. makes me cry

What do this problem mean ?

David Motson on 10 Jan 2020

@Cody Team, does this need to be a Cody Challenge? It's a pretty rubbish problem

Rik on 13 Jan 2021

I would vote for removal from this list as well. There is even another one about US states... This is so infuriating and repetitive I almost resorted to echoing assert.

Marco Riani on 3 Jan 2022

I too would vote for removal from this list.
I can understand strtrim but not that in the solution there must be exactly the same amount of (say) 7 spaces between two consecutive words.

Terrible test suite. The test suite fails if you don't replace every removed entry with exactly one space.

The pass criteria should not be specific to the number of spaces that are left instead of the omitted state names. This beats the purpose of the exercise. There should either be no extra spaces left in the solutions, or it should not be specific to how the author of the challenge solved the problem.

Inconsistent behavior - if you are going to make a question like this, make it representative of what would actual be done and not some arbitrary undocumented rules like "replace a two-word state name with a space"

I am a new Matlab programmer and don't know much about regexp. Is it not good to use that?

goc3 on 3 Aug 2021

@Apurbo, regexp is a great function for its intended application. Unfortunately, some Cody users have exploited that function, and a few others, to cheat—the comment in this solution is referring to that widespread problem.
