How does dynamic sizing work in hash tables in C++?
Dynamic sizing in hash tables allows the table to resize when the load factor exceeds a certain threshold, improving performance.
What is a load factor?
The load factor is the ratio of the number of elements in the hash table to the size of the table. It helps determine when to resize.
How do I implement dynamic resizing in my hash table?
You can implement dynamic resizing by creating a new larger array and rehashing all existing elements into it when the load factor is exceeded.
What are the performance implications of resizing?
Resizing can be costly since it involves rehashing all elements, but it improves average lookup and insertion times in the long run.
