Scheme (DrRacket)

;Q1
; enter your code here:

; Test cases
(display "AND-Gate Output\n")
(AND-gate 0 0)
(AND-gate 0 1)
(AND-gate 1 0)
(AND-gate 1 1)

Write three Scheme procedures to simulate these three gates: AND, OR, and NOT, shown
in the diagram in Figure 1. Test your procedures using all possible input combinations.
Hint: Lecture slides showed the implementation of a not-gate in Scheme.
