Implement 4-bit Binary -to -Gray, Gray -to -Binary code converter.   

sample input

 Input:  For circuit 1: Binary code (B3B2B1B0) = 0101 

Input:  For circuit 2: Gray code (G3G2G1G0)= 0111  

expected output 

Output: For circuit 1: Gray code (G3G2G1G0)= 0111 Output: For circuit 2: Binary code (B3B2B1B0) = 0101 2 Theory Gray Code: Gray code is a binary numeral system where two successive values differ in only one bit.
