What are some collision resolution techniques in C++?

Collision resolution techniques are methods used to handle situations where two or more objects occupy the same space in a data structure. Common techniques include chaining, open addressing, and linear probing.

Can you explain how chaining works?

Sure! Chaining involves maintaining a list of all elements that hash to the same index. When a collision occurs, the new element is simply added to the list at that index.

What about open addressing?

Open addressing resolves collisions by finding another open slot within the array. Techniques include linear probing, quadratic probing, and double hashing.

Which technique is generally more efficient?

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