TL;DR Cantor pairing is a perfect, reversible, hashing function from … Web$\begingroup$ @Joppy is there a way to generate a hash as you add new numbers to the list some how? If you know the hash for {3,4,5,6} and then add say 17 so you now how {3,4,5,6,17} would you have to iterate the whole list to get a new hash or is there a simple way to update the hash ? $\endgroup$ –
