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

To answer the question regarding collision resolution techniques in hash tables, let's first identify the options given:

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

Analysis of the Options

1. Chaining: This is a common method for handling collisions in hash tables. In this technique, each bucket or slot in the hash table contains a linked list of keys that hash to the same index.

2. Open Addressing: This technique involves finding another open slot within the hash table when a collision occurs. Methods like linear probing, quadratic probing, and double hashing fall under this technique.

3. Double Hashing: This is actually a type of open addressing technique where a second hash function is used to determine the step size for finding an open slot.

4. Linear Probing: This is a specific method of open addressing where the next slot is checked in a sequential manner until an empty slot is found.

Final Conclusion

All of the provided options—Chaining, Open Addressing, Double Hashing, and Linear Probing—are common collision resolution techniques. However, since the question asks for the one that is NOT a common technique, the answer would be inferred based on interpretation.

Typically, "Open Addressing" is a category, not a specific technique itself. Therefore, Open Addressing could be considered the answer, but since it's phrased as a resolution technique, the answer would be none of the options are correct because they all represent common techniques in some way.

To clarify single distinct techniques that do not commonly appear: If you are looking for a technique that does not belong here, it would likely be something like "Quadratic Probing" or some other less common method not listed.

Final Answer

None of the above; all listed options are common collision resolution techniques.
