Calculating the similarity of two lists

Question

I have two lists:

eg. a = [1,8,3,9,4,9,3,8,1,2,3] and b = [1,8,1,3,9,4,9,3,8,1,2,3]

Both contain ints. There is no meaning behind the ints (eg. 1 is not \'cl

Answer 1

Just use the same algorithm for calculating edit distance on strings if the values don't have any particular meaning.
