WebMar 11, 2024 · Hash tables are auxiliary data structures that map indexes to keys. However, hashing these keys may result in collisions, meaning different keys generate the same index in the hash table. We’ll demonstrate how linear probing helps us insert values into a table despite all collisions that may occur during the process. WebPerformance of Hash Maps 27 • put(key, value) • get(key) • remove(key) If load factor is less than 1 and if hash function is good, then these operations are O(1) “in practice”. This beats all potential map data structures that I considered last lecture !!! If we have a bad hash, we can choose a different hash function.
