Problem the gray similar code

How do i approch the Gray Similar Code with pigeon principle

@imsaurabh
For each adjacent pair take XOR
The result will be 1 of 64 possible numbers after the xor
So after 65 such pairs you’ll get an answer definitely since 65 numbers and 64 possible values means atleast one value will occur twice
