How do hash tables handle collisions in C++?

In C++, hash tables typically handle collisions using methods like chaining or open addressing. Would you like to know more about these methods?

Yes, can you explain chaining?

Chaining involves storing multiple elements at the same index using a linked list. When a collision occurs, the new element is added to the list at that index.

What about open addressing?

Open addressing finds another open slot in the array when a collision occurs. Techniques include linear probing, quadratic probing, and double hashing.

Which method is generally more efficient?

It depends on the load factor and the specific use case. Chaining can be more efficient with high load factors, while open addressing can be better for lower load factors.
