WebJan 25, 2024 · Search and insert of the hash table. The idea of hashing is to distribute the entries (key/value pairs) across an array of buckets. Given a key, the algorithm computes an index that suggests where the entry can be found: index = f (key, array_size) Often this is done in two steps: hash = hashfunc (key) index = hash % array_size.
