Practice 2.40This question wants us to write a procedure that passes an integer n and then returns a sequence pair (i, j) Unique-pairs, and then uses the definition of the prime-sum-pairs on the previous page. At this point we need to pay attention to which piece of code in prime-sum-pairs expresses this meaning. Yes, it's the flatmap function. So we write it into the unique-pairs .(Define (unique-pairs N) (Flatmap (Lambda (i) (Map (Lambda (j) (List I J)) (enumerate-interval 1 (-I 1)))) (enum
