What are the performance characteristics of hash tables?
Hash tables offer average-case O(1) time complexity for lookups, insertions, and deletions, but can degrade to O(n) in worst-case scenarios.
What factors can affect the performance of a hash table?
Factors include the choice of hash function, load factor, and collision resolution strategy. A poor hash function can lead to many collisions.
How can I improve the performance of my hash table?
You can improve performance by using a better hash function, resizing the table when the load factor is high, and implementing efficient collision resolution methods.
Are there any alternatives to hash tables?
Yes, alternatives include binary search trees, arrays, and linked lists, each with their own performance characteristics depending on the use case.
