How to find if two numbers are consecutive numbers in gray code sequence

Question

I am trying to come up with a solution to the problem that given two numbers, find if they are the consecutive numbers in the gray code sequence i.e., if they are gray code neig

Answer 1

If two numbers are in gray code sequence, they differ by one binary digit. i.e the exclusive OR on the two numbers returns a power of 2. So, find XOR and check if the result is a power of two.

python 3.8

a=int(input())
b=int(input())
x=a^b 
if((x and (not(x & (x - 1))) )):
    print("True")
else:
    print("False")
