hopscotch is a way of resolving hash collisions using open addressing
and is also useful in implementing a concurrent hash table.
"Cuckoo hashing is a scheme in computer programming for resolving hash collisions of values of hash functions in a table, with worst-case constant lookup time." - https://en.wikipedia.org/wiki/Cuckoo_hashing
