How can I optimize hash functions in C++?

Optimizing hash functions in C++ can involve several strategies, such as improving the distribution of hash values, reducing collisions, and enhancing performance. What specific aspect are you looking to optimize?

I'm interested in reducing collisions. What techniques can I use?

To reduce collisions, you can use techniques like choosing a better hash function, using prime numbers for table sizes, and implementing double hashing or chaining. Would you like examples of these techniques?

Yes, please provide an example of a good hash function.

A simple yet effective hash function is the MurmurHash. It's known for its good distribution and speed. Would you like to see a code example?

Yes, that would be great!

Here's a basic implementation of MurmurHash in C++... [code snippet] Let me know if you need further explanation!
