Please show me in scheme please.

1.

A) Write a function in Scheme to return 1, 0, +1 depending on two parameters a and b:

a < b return 1

a > b return +1

a = b return 0

b) Write a recursive function in Scheme, called get-element which takes two parameters, an index and a list. The function returns the element at the given index position in the list or #f if element is not contained. Indices start at 1 and go to the length of the list.

C) Question: How would you change the function so it returns the whole list if the element is not contained?
