Question 1

What are the common collision resolution techniques in a hash table?

Accepted Answer

Common collision resolution techniques include separate chaining (using linked lists for each bucket) and open addressing (probing for the next available slot, e.g., linear probing, quadratic probing, or double hashing).

Question 2

What is the difference between a hash map and a hash table?

Accepted Answer

In many languages, the terms are used interchangeably. However, in Java, `Hashtable` is a synchronized legacy class, while `HashMap` is a non-synchronized, more modern implementation.
