Question: What is the main disadvantage of using open addressing for collision resolution?

Options:

Correct Answer: It can lead to clustering

Solution:

Open addressing can lead to clustering, where a group of consecutive slots are filled, which can degrade performance during searches and insertions.

What is the main disadvantage of using open addressing for collision resolution?

Step 1: Understand what open addressing is. It is a method used in hash tables to resolve collisions when two keys hash to the same index.
Step 2: Know that when a collision occurs, open addressing finds the next available slot in the array to store the new key.
Step 3: Realize that if many keys collide, they will fill up consecutive slots in the array.
Step 4: This filling of consecutive slots is called clustering.
Step 5: Understand that clustering can make it harder to find empty slots for new keys and can slow down searches for existing keys.
Step 6: Conclude that the main disadvantage of open addressing is that clustering can degrade performance during searches and insertions.
