You will reimplement the Quicksort given in textbook and lecture slides. In the given example, the first (left-most) element of the given list is selected as the pivot. In this question, you must choose the second element of the list as the pivot. Hint: You can represent the input list into pairs: [First | [Pivot Tail]]. You must write comments to indicate the size-n problem, stopping condition and its return value, size m-problems, and construction of the size-n problem from size-m problems. [20 points) Test case: | ?- qsort2([8, 3, 4, 12, 25, 4, 6, 1, 9, 22, 6), Sorted). It returns: Sorted = (1,3,4,4,6,6,8,9,12,22,25) Quick Sort Code in Prolog asort([],[)) :-! % empty list is already sorted qsort([Pivot/Tail], Sorted):- % Take first number as pivot split(Pivot, Tail, L1, L2), qsort(L1, Sorted1), % sort first part qsort(L2,Sorted2), % sort second part append(Sorted 1, [Pivot|Sorted2], Sorted). split(_,0,0,0). split(Pivot,[X|T],[X|Le], Gt):- X= Pivot, split(Pivot, T, Le, Gt). % stopping condition % take first from Tail % and put it into Le % take first from Tail % and put it into Gtchs 9/2002
