What factors affect the performance of dictionaries in programming?

The performance of dictionaries is influenced by factors like hash function efficiency, load factor, and collision resolution.

How does the choice of hash function impact performance?

A good hash function minimizes collisions, leading to faster lookups and insertions, while a poor one can degrade performance.

What is load factor and why is it important?

Load factor is the ratio of the number of entries to the number of buckets. A high load factor can lead to more collisions.

Can you explain collision resolution methods?

Sure! Common methods include chaining, where collisions are stored in a linked list, and open addressing, where alternative slots are searched.

Are there any performance benchmarks for dictionaries?

Yes, benchmarks vary by implementation and use case, but generally, dictionaries offer average O(1) time complexity for lookups.
