Question

Using Racket to produce a list of two-element lists consisting

of one value from the first list and one value from the second
list. For example '(1 2) and '(a b) -> '((1 a) (1 b) (2 a) (2
b))

Answer 1

To produce a list of two-element lists consisting of values from two different lists in Racket, you can use nested for loops and the list function.

Step-by-step explanation:

In Racket, you can use the for loop to generate a list of two-element lists using elements from two different lists. To achieve this, you can use nested for loops. Here's an example:

(define list-one '(1 2))
(define list-two '(a b))
(define result '())
(for ([x list-one])
(for ([y list-two])
(set! result (cons (list x y) result))))
(reverse result)

This code uses for loops to iterate over each element of list-one and list-two. It then appends a two-element list ((list x y)) consisting of one value from list-one and one value from list-two to the result list. Finally, the result list is reversed to match the desired output.
