matlab space error problem

does anyone know why my output doen't have space between two words

[Brent Kostich]

What exactly are the inputs twisted4 and seg4?

[Brent Kostich]

More to your question, strcat removes any trailing white-space. If you have trailing white-space use horzcat instead. My guess is that you don't have any leading or trailing white-space, in which case you will have to add it into the looping routine.

oh my question is add the space white between words. Because the Expected value is i love georgia tech" But my answer is "i lovegeorgiatech"

[Brent Kostich]

What exactly is your function supposed to do?

[Maria]

its just given a string that is scrambled up and a segment of the string, representing the scrambled part. The string can be unscrambled by moving the segment given to the end of the string. Locate where the segment is in the string. Then, delete that segment and append it to the end of the string to "untwist" it.

[Brent Kostich]

I think I understand what you are trying to do, but I think you need more code to achieve your desired result. If you give me an example for str and segment I can show you the fix.

[Maria]

I dont know about this. But there is a test case

untwisted = tongueTwister('Raodp G ', 'od')

untwisted → Rap God

[Brent Kostich]

That example works because all you need to do is move the 'od' to the end.

If you removed the space so it was 'RaodpG', then your anwer would be 'RapGod'

The function would only work on very specific cases, it would not work on general cases.

[Maria]

So this is right?

[Brent Kostich]

Did you not write this function? If you are asking me if your own test case is right, then I take it you have no idea what that code is doing.

If that is true, then no one can help you.

[Maria]

gotcha it. I used horzcat instead of stracat and it works ! thanks !

Answer 1

[Fangjun Jiang]

From "help strcat"

For character array inputs, strcat removes trailing ASCII white-space

characters: space, tab, vertical tab, newline, carriage return, and

form-feed. To preserve trailing spaces when concatenating character

arrays, use horizontal array concatenation, [s1, s2, ..., sN]

Answer 2

[Steven Lord]

You can use concatenation as Fangjun Jiang and Brent Kostich suggested. I'd probably use join instead.

join(["I", "love", "Georgia", "Tech"])
