+/**
+ n number theory, a vampire number (or true vampire number) is a composite natural number with an even number of digits,
+ that can be factored into two natural numbers each with half as many digits as the original number
+ and not both with trailing zeroes, where the two factors contain precisely
+ all the digits of the original number, in any order, counting multiplicity.
+ The first vampire number is 1260 = 21 × 60.
