Hamming Distance:

Hamming distance between two strings of equal length is the number of positions at which the relative symbols are different.

example: 1    1    0    1

                   1    0    0    1 

                --------------------

                         1- mismatched, relative symbol is different.

So, the Hamming distace is 1.
