Write a Scheme procedure (manhattan a b) which, given two pairs representing points on the Cartesian coordinate system, returns the Manhattan distance between the two points.

Write a Scheme procedure called (integer->binary x) that converts an integer to a binary number represented as a list of 0s & 1s. For example: (integer->binary 20) (1 0 1 0 0)

OUTPUT:

"Question 1: manhattan" 7 17 "Question 2: integer->binary" (1) (1 1 1 1) (1 0) (1 0 1 0 1 0 1 0 1 0)
