What is open addressing in hashing?

Open addressing in hashing is a collision resolution technique where all the elements are stored directly in the hash table itself. When a collision occurs, the algorithm searches for the next available slot in the hash table to store the element. This is done by probing through the table using a predefined sequence until an empty slot is found. The advantage of open addressing is that it avoids the need for additional data structures to store collided elements, but it can lead to clustering and increased search time if not implemented properly.
