Problem 88. It dseon't mettar waht oedrr the lrettes in a wrod are.

Idk why 'ABCD-EFGH' should be ' '... Isnt it better to deal with this in a way that sOut='ACBD-EGFH' ?

Apologies, I must have forgot to update the test suite before saving.
It should be okay now.

Since the original author did not describe how hyphenated words should be treated, I won't be able to them as test cases.

Test 1 doesn't work, I literally have the same result and it fails, but test 2 passes

Your function produces sOut in string format (in the last line of the function). The test suite defines the variables as character arrays instead of strings. These two data types cannot be directly compared—i.e., you'll have to return a character array.

Also, when I run your function, it returns "hello" rather than "hlleo".

I've tried the assert in MATLAB on my desktop and it doesn't throw an error... so I'm not really sure where it's gone wrong here. I'm guessing it's something tiny I've missed. Any help?

Which version of MATLAB are you using on your desktop? I tried running your solution on MATLAB desktop version 2019a and the solution is failing with correct assertions. In order to figure out the version of MATLAB, command "ver' will get you the version.

The version of matlab is not going to affect the result. This solution removes punctuation from the input, so the '.' at the end of sentence in the second test is incorrectly removed.

Couldn't work out how to leave the punctuation in :(

Brilliant!

The test suite should add commas and other punctuation.
