Which of the following is NOT a common collision resolution technique?Group of answer choicesOpen AddressingChainingDouble hashingLinear probing

The question is asking which of the given options is NOT a common technique used to resolve collisions in hash tables. The options provided are:

1. Open Addressing
2. Chaining
3. Double Hashing
4. Linear Probing

Let's go through each option:

1. Open Addressing: This is a method where if a collision occurs, we look for another open slot to hold the item that caused the collision.

2. Chaining: This is a method where each slot of the hash table is allowed to hold a reference to a collection (or chain) of items. Collisions are resolved by storing the new item in the chain.

3. Double Hashing: This is a method of open addressing where the interval between probes is computed by another hash function.

4. Linear Probing: This is a method of open addressing where the interval between probes is fixed (usually 1).

All of the options provided are indeed common techniques used to resolve collisions in hash tables. Therefore, none of the options is the correct answer to the question as all are common collision resolution techniques.
