Hash table chaining time complexity
Did you know?
WebA hash table is a data struture commonly used to associate keys with values to implement dictionaries or to test if a key is part of a set of keys to implement set operations. The best hash table is the one that enables these operations at the lowest cost. Cost in computing essentially is two-dimensionsional, time and space. WebHash tables suffer from O(n) worst time complexity due to two reasons: If too many elements were hashed into the same key: looking inside this key may take O(n) time. …
