What is a hash table collision and how can it be resolved?
A hash table collision occurs when two different keys hash to the same index. This can be resolved using methods like chaining or open addressing.
Can you explain chaining in more detail?
Sure! Chaining involves maintaining a list of all entries that hash to the same index. When a collision occurs, the new entry is added to this list.
What are the advantages of using open addressing?
Open addressing stores all entries directly in the hash table. It can be more space-efficient and can lead to faster lookups if the table is not too full.
Are there any downsides to these methods?
Yes, chaining can lead to longer search times if many collisions occur, while open addressing can suffer from clustering, which affects performance.
