Hash-table: Basic Idea Many applications require a Dynamic Set that supports only the dictionary operations Insert, Search, and Delete. Searching for an element in a hash table can take as long as searching for an element in a linked list— Θ(n) time in the worst case. Under reasonable assumptions, the average time to search for an element in a hash table is Θ(1). MA Jun (Institute of Computer Software) Problem Solving May 10, 2022 2 / 34
