FAQs

Question: What is a hash function?
Answer: A hash function is a function that converts an input (or 'key') into a fixed-size string of bytes, typically used for indexing data in hash tables.

Question: Why is collision resolution important in hash tables?
Answer: Collision resolution is crucial because it ensures that multiple keys can be stored in the hash table without losing data or causing errors in retrieval.
