can anyone check my solution 1292494. it look like when i convert to string it add a space before EOL (ascii 10).
I don't find from where it came

Maybe it comes from the new matlab strings introduced only recently in R2017a. You can notices them by the 'string' constructor and the double quotes in the test cases.
String concatenation and some other things seem to work differently for them, than for the good old char arrays.

Yona on 18 Oct 2017

maybe you right. the question is how i can remove it after or during the construction?

Yona on 18 Oct 2017

I found the difference and add a patch (cost me 50 in length)

When I run the assertions in MATLAB, they all come out true. Could you please help me figure out what is going wrong in Cody?

The problem is with new "string" type in Matlab and "Starting in R2017a, you can create strings using double quotes" --manual.

Thus length("CODY") = 1 vs strlength("CODY") = 4
and string(["aa" "bb" "cc"]) is 1x3 string array which is not correct answer. (check strjoin function)

Getting this one right on a version of MATLAB without the "string" capability was painful. I didn't know you couldn't convert a string to numbers by doing the string-0 trick like you can with char...

I don't find from where it came and don't see where i can remove it.
