Date & Time Due:

Your marked coursework and feedback will be available to you

on:

If for any reason this is not forthcoming by the due date your module leader will let you know why and when it can be expected. The Head of Studies (headofstudies-tec@dmu.ac.uk ) should be informed of any issues relating to the return of marked coursework and feedback.

Note that you should normally receive feedback on your coursework by no later than 20 University working days after the formal hand-in date, provided that you have met the submission deadline.

06 Apr 2018

When completed you are required to submit your coursework via:

1. Upload script file to Blackboard

Late submission of coursework policy: Late submissions will be processed in accordance with current University regulations which state:
“the time period during which a student may submit a piece of work late without authorisation and have the work capped at 40% [50% at PG level] if passed is 14 calendar days. Work submitted unauthorised more than 14 calendar days after the original submission date will receive a mark of 0%. These regulations apply to a student’s first attempt at coursework. Work submitted late without authorisation which constitutes reassessment of a previously failed piece of coursework will always receive a mark of 0%.”

Academic Offences and Bad Academic Practices:

These include plagiarism, cheating, collusion, copying work and reuse of your own work, poor referencing or the passing off of somebody else’s ideas as your own. If you are in any doubt about what constitutes an academic offence or bad academic practice you must check with your tutor. Further information and details of how DSU can support you, if needed, is available at: http://www.dmu.ac.uk/dmu-students/the-student-gateway/academic-support-office/academic- offences.aspx and http://www.dmu.ac.uk/dmu-students/the-student-gateway/academic-support-office/bad-academic- practice.aspx

Tasks to be undertaken:

Provide a solution for each of the five questions below. You must add a brief comment for each function explaining how the function works.

Question 1 (4 points): Write a function that checks if a given number is a “perfect number” using a list comprehension. A number x is considered perfect if all of its factors add up to x, e.g. 6 is perfect because 1 + 2 + 3 = 6. The output should be a Bool. Include the type signature of the function.

Question 2 (6 points): Write a function that merges two ordered lists of numbers into one using recursion and pattern matching. The end result should also be ordered. Include the type signature of the function.

Question 3 (4 points): Write a function that checks if two given student P-numbers (e.g. “P09876543” and “P17234567”) are from the same year (i.e. they both start with the same two digits after the initial P). The output should be of type Bool. Include the type signature of the function.

Question 4 (6 points): Write a function that calculates your tax band based on a given yearly income using a guarded equation. Your output should be a string. Include the type signature of the function. You can check the UK’s tax rates on the government website https://www.gov.uk/income-tax-rates.

Question 5 (5 points)
Write a function, group n xs, that groups a string, xs, into a list of substrings of a size n. If necessary, the last string may contain fewer than n characters. Thus, group 5 “abcdefghijklm” = [“abcde”, “fghij”, “klm”]

Deliverables to be submitted for assessment:

You are required to submit one Haskell script file. Put all of your code and comments into a Haskell script (p12345678.hs) (Use your p-number) so that your entire solution to the assignment can be uploaded as one text file.

How the work will be marked:

Tutors will run each of your solutions using GHCi. Each function will be checked for correctness. The code comments are really important as these will indicate your understanding of the code you have written. Your comments will be read by the marker and checked for understanding. Marks are then assigned for each question.
