FAQs

Question: What is a hash function?
Answer: A hash function is a mathematical algorithm that transforms input data into a fixed-size string of characters, which is typically a hash code.

Question: Why is collision resolution important in hash tables?
Answer: Collision resolution is crucial because it ensures that multiple keys can be stored in a hash table without losing data, maintaining the efficiency of data retrieval.

Question: How does hashing improve data retrieval speed?
Answer: Hashing allows for constant time complexity on average for data retrieval, making it much faster than other data structures like arrays or linked lists.
