Can you explain what hash table collisions are?
Sure! A hash table collision occurs when two different keys hash to the same index in a hash table.
Why do collisions happen in hash tables?
Collisions happen due to the limited size of the hash table and the nature of the hash function, which can map multiple keys to the same index.
How are collisions handled in hash tables?
Collisions can be handled using methods like chaining, where each index points to a list of entries, or open addressing, where we find another open slot.
What are the pros and cons of these collision resolution methods?
Chaining is simple and effective but can use more memory. Open addressing is space-efficient but can lead to clustering and longer search times.
