Given a very long string composed of numbers as characters, find the four character substring that has the largest multiple. For example, given the string "809723", the two char substring with the largest multiple is "97", having a multiple 9*7 = 63.
Merge to sorted arrays into second array, both arrays has N elements, but second array size is N * 2. So you merge both arrays in second array in a sorted way.

Implement a method 'find' that will find the starting index (zero based) where the second list occurs as a sub-list in the first list. It should return -1 if the sub-list cannot be found. Arguments are always given, not empty. Sample Input 1 list1 = (1, 2, 3) list2 = (2, 3) Sample Output 1 1 Explanation As second list (2, 3) is sub-list in first list (1, 2, 3) at index 1 Sample Input 2 list1 = (1, 2, 3) list2 = (3, 2) Sample Output 2 -1
