b. Program Requirements Write a Haskell function that will: - Accept a list of items as the parameter to the function - Sort the list using a QuickSort. You must code the sort algorithm, not use a library routine. - Return the sorted list Don't overcomplicate this! My reference version is 7 lines long including blank lines. It doesn't need to be efficient (although that is good), it just needs to sort. You also don't need to read in anything! I just want the function. c. Program Environment The function will be run using the ghci interactive shell. You are NOT expected to do I/O in this function
