What have you tried so far?
If you submit other people's work as your own work this is plagiarism, a very serious offence in most countries. We are volunteers who help answer questions about using MATLAB. What is your question about MATLAB?

If this IS NOT part of a homework assignment, call the isdst function with a datetime object that has a nonempty TimeZone property as input.
If this IS part of a homework assignment, Stephen and Adi are correct. If you show what you've done and ask a SPECIFIC question you may receive some guidance. [You may also want to use the isdst function to check your code; provide equivalent days to your function and to isdst and confirm their answers agree.]

From what I see, the question, even if homework, does not specifically prohibit the use of isdst() or other built-in functions, so I think it's possible to use isdst() as part of the solution. Some automated/computerized graders simply put in test inputs and look at test outputs to see if they're correct and never really examine what's going on inside. Though, doing it the "manual" way instead of using isdst() might be a good learning experience.
To get the user input (the date) one might use inputdlg().
