strjoin, string, remove a single space, while combining variables.

I have to do this in this manner for a hw question, I know there are other ways to acomplish the same thing....

X = strjoin([ "The" , "cat" ], " ")
Y = strjoin([ "over" , "the" , "fence" ], " ")
Z = strjoin([ X ,"jumped", Y ,"." ], " ")

"Z" has a space between the end of string "Y" and the added period, I need to remove just that space while maintaining the rest of the spaces between the other strings.

How do I get.....

"The cat jumped over the fence." % no space between "fence" and "."

Join one fewer item in Y, and strcat() or + it on to the end.

If you absolutely must use only strjoin, then join one fewer item into Y, and strjoin the result with "" (empty string) using "." as the joining character.

Thank you for response, I must use strjoin, but I'm not sure what you mean by "" (empty string) using "." as joining character

strjoin([A, ""], ".")
