WebParticularly the theorem which says that given an open-address hash table with load factor $\alpha = n/m < 1$, the expected number of probes in an unsuccessful search is at most $1/(1-\alpha)$, assuming uniform hashing. WebA hash table is a container data structure that allows you to quickly look up a key (often a string) to find its corresponding value (any data type). Under the hood, they’re arrays that are indexed by a hash function of the key. A hash function turns a key into a random-looking number, and it must always return the same number given the same key.
