Separate chaining: In this technique, a linked list is maintained at each slot in the hash table. When a collision occurs, the collided elements are stored in the linked list at that slot, allowing multiple elements to reside at the same position.
-
Open addressing: In this technique, when a collision occurs, the algorithm probes for the next available slot within the hash table until an empty slot is found. This involves various strategies such as linear probing (moving linearly through the table) or quadratic probing (using a quadratic function to determine the next slot to check).

What are the two broad classes of collision resolution techniques explain?
The two broad classes of collision resolution techniques in hashing are open addressing and separate chaining. Open addressing involves storing all the key-value pairs directly in the hash table itself, handling collisions by probing for an open slot. Separate chaining involves storing collisions in separate data structures (like linked lists or binary trees) at the same index in the hash table.
What are the different types of collision resolution techniques?
Some common collision resolution techniques include linear probing, chaining, and double hashing. Linear probing involves searching for the next available slot in the hash table when a collision occurs. Chaining involves storing multiple values in the same slot in the hash table. Double hashing uses a secondary hash function to calculate an offset when a collision occurs.
What is collision number?
Collision number refers to the minimum number of comparisons needed in a data structure to resolve all potential collisions that may occur while inserting elements into a hash table or hash map. It helps determine the efficiency and performance of handling collisions in hashing algorithms.
Where is the millimeter on a ruler?
A millimeter is typically marked between each centimeter increment on a ruler. It is the smallest unit of measurement on most rulers.
What is a pound key?
A pound key, also known as the number sign or hash symbol, is represented by the "#" symbol on a phone or keyboard. It is commonly used to input numeric digits in phone systems or to create a tag on social media platforms.
