Write a function named split-list in Scheme that takes a list and a length as input and returns two lists: (1) The first length elements of the input list, and (2) the remainder of the input list. Hint: Use a helper method with an "accumulator" parameter. For example, • (split-list '(a b c d e f g) 0) should return '(() (a b c d e f g)) • (split-list '(a b c d e f g) 1) should return '((a) (b c d e f g)) (split-list '(a b c d e f g) 3) should return '((a b c) (d e f g)) (split-list '(a b c d e f g) 7) should return '((a b c d e f g) ())

'Split List' in Scheme:

 

Write a function named split-list in Scheme that takes a list and a length as input and returns two lists:
(1) The first length elements of the input list, and (2) the remainder of the input list. Hint: Use a helper
method with an "accumulator" parameter.
For example,
• (split-list '(a b c d e f g) 0) should return '(() (a b c d e f g))
• (split-list '(a b c d e f g) 1) should return '((a) (b c d e f g))
• (split-list '(a b c d e f g) 3) should return '((a b c) (d e f g))
• (split-list '(a b c d e f g) 7) should return '((a b c d e f g) ())
