Description: You are given two arrays a1 and a2 of strings. Each string is composed with letters from a to z. Let x be any string in the first array and y be any string in the second array. Find max(abs(length(x) − length(y))) If a1 and/or a2 are empty return -1 in each language except in Haskell (F#) where you will return Nothing (None). Example: a1 = ["hoqq", "bbllkw", "oox", "ejjuyyy", "plmii..
