What factors affect the performance of hash maps in C++?
The performance of hash maps in C++ can be influenced by factors like load factor, hash function quality, and collision resolution.
How does the load factor impact performance?
A higher load factor can lead to more collisions, which may slow down operations like insertions and lookups.
What is a good hash function for C++?
A good hash function should distribute keys uniformly across the hash table to minimize collisions. Common choices include std::hash.
Can you explain collision resolution techniques?
Sure! Common techniques include chaining, where each bucket points to a list of entries, and open addressing, where you find the next available slot.
