not sure what your asking, or if it's for me, but in the problem I raised each vertex is a string of alphanumeric characters

    or if it's for me

    I replied to your post; it is for you.

    not sure what your asking,

    Your data showed single characters: @array1 = [A,B,F,G]; if that was representative of your real data, there is an optimisation that could be used.

    each vertex is a string of alphanumeric characters

    The solution I posted will work for strings (or any other kind of data) and is the fastest solution possible. Over 50 times faster than 1169738; and correct.
