Question: In this exercise, we will look at sorting in Prolog.

a. Write Prolog clauses that define the predicate sorted (L ) , which is true if and only if list L is sorted in ascending order.

b. Write a Prolog definition for the predicate perm (L , M) , which is true if and 113nly ifL is a permutation of bT.

c. Define sort (L, M) (M is a sorted version of L) using perm and sorted.

d. Run sort on longer and longer lists until you lose patience. What is the time complexity of your program?

e. Write a faster sorting algorithm, such as insertion sort or quicksort, in Prolog.
