A Hamming number is a positive integer of the form 2i3j5k, for some nonnegative integers i, j, and k. They are often referred to as regular numbers. More info at: https:en.wikipedia.orgwikiRegularnumber. This function creates an ordered list of n length as requested, and afterwards returns the last value of the list. It must be given a positive integer. :param nelement: The number of elements on the list :return: The nth element of the list  hamming5 1, 2, 3, 4, 5  hamming10 1, 2, 3, 4, 5, 6, 8, 9, 10, 12  hamming15 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24
