Assignment 5
CS|E 141 & Inf4mtx 101: Programming Languages
Place your answers to the following questions in a file named, assignment5.hs Question 1:
Write a Haskell function called insert that takes two parameters (a list and a number). You may assume that the list consists of 0 or more numbers that are in order. The function should return a list that would result from inserting the number into the list into the appropriate place to keep the list in order. For example,
>insert [2, 4, 6, 8] 5 should return [2, 4, 5, 6, 8]. Question 2:
Write a polymorphic Haskell function called insertSort that takes one parameter (a list of elements). The function should return the list that would result from sorting the list using insertion sort. Note: the insert function should be useful here, as would an auxiliary function.
Question 3:
Write a function merge :: (Ord a) => [[a]] -> [a] that takes a finite list of sorted finite lists and merges them into a single sorted list. A ¡°sorted list¡± means a list sorted in increasing order (using <); you may assume that the sorted lists are finite. For examplemerge [[1, 2, 3]] = [1, 2, 3]merge [[1, 3, 5, 7], [2, 4, 6]] = [1, 2, 3, 4, 5, 6, 7]merge [[1,3,5,7], [2,4,6], [3,5,9,10,11,12]] =[1,2,3,3,4,5,5,6,7,9,10,11,12]take 8 (merge [[1, 3, 5, 7], [1,2,3,4,5,6,7,8]]) = [1, 1, 2,3, 3, 4, 5, 5]Question 4:Write and test the definition of a (polymorphic) Haskell function ‘center’ that takes three arguments, a list arg1 of type [a], a width arg2 of type Int, and a fill item arg3 of type a, and returns a list of length arg2 of type [a] containing list arg1 centered within fill items (i.e., the difference between the number of items preceding arg1 and those following arg1 is at most 1). For instance, center “abcd” 7 ‘-‘ could yield “–abcd-” or “-abcd–” (as you choose).Question 5:Write and test the definition of a Haskell function ‘largest’, which finds the largest element of a list, but is implemented using higher-order functions and/or operator sections as appropriate.
