How can I optimize hash table performance?

How can I optimize hash table performance?

To optimize hash table performance, consider using a good hash function, managing load factors, and resizing appropriately.

What are some common hash functions I can use?

Common hash functions include division method, multiplication method, and universal hashing. Each has its pros and cons.

How does load factor affect performance?

The load factor affects performance by determining how full the hash table is. A higher load factor can lead to more collisions.

What strategies can I use to handle collisions?

You can handle collisions using chaining, open addressing, or double hashing. Each method has different trade-offs.

When should I resize my hash table?

You should resize your hash table when the load factor exceeds a certain threshold, typically around 0.7 to 0.75.
