In this lab, you will learn to build gray-code encoder and decoder. You will also learn to build a 7-segment display encoder
Part 1. Construction of a Combinational Logic for the Gray-code ENCODER
Design a combinational logic circuit that converts three-bit binary code counter to three-bit gray-code counter (Gray Code ENCODER)

Part 3. 7-segment display
Given a number between 0 and 9 as input, output the 7-segment display code
