Can you give us sample inputs to use, that result in the error you see? (Even better is to just code them in, instead of having us go through inputs.)
What is the full error message you are getting?

apostrophe is not a valid character in a file name for a m file.

Hi,
It is my understanding that you are getting the error "MATLAB can only run a file with a valid name" while running a script.
As your script name contains an apostrophe, you are getting this error.
File names must start with a letter, and can contain letters, digits, or underscores.
More information on specifying the file name can be found here: https://in.mathworks.com/help/matlab/matlab_env/specify-file-names.html

Unable to run file.
MATLAB file names must start with an alphabetic character and can contain up to 63 alphanumeric characters or underscores.

Not enough input arguments.
Error in Exercise_2 (line 4)

Your Exercise_2 has been defined as a function that requires at least one input parameter, referred to as count but you are trying to run the function without providing any input.
