Consider a program which is designed to accept a non-empty list of integers as input. The input list may contain duplicated integers. This program is intended to output the elements of the input list in ascending order without duplication. For example, if the input list is [3, 9, -20, 16, 9, 7, -5, 28, 20, 5, -20], then the output will be [-20, -5, 3, 5, 7, 9, 16, 20, 28]. In this assignment, you are required to do the following: 1. Describe seven metamorphic relations for this problem. Provide an example to each of your metamorphic relations. Your defined metamorphic relations shall not contain redundant metamorphic relations. (70%) 2. Which is the most effective metamorphic relation amongst your defined metamorphic relations? Provide justifications for your answer. (30%) 3. Submit a self-contained, complete, comprehensive, and typed report. Your report must use single column, 12-point font size on A4 papers. Your report must contain no more than three pages. Coverage page is not required, but your submission must contain your full name and your student number on the first line of page 1.
