Hash Tables Chaining with List Heads Quiz Online Practice Test

1. What component is used to map keys to addresses in a hash table?

Hash function

Separate chaining

Open addressing

Chaining with a linked list

2. How does a hash table provide an advantage compared to a linked list?

Faster data access

Simpler implementation

More efficient for a small number of entries

Better locality of reference

3. Which characteristic is most desirable in a hash function?

Minimal collisions

High collision rate

Low space usage

Simplicity of implementation

4. How efficient is the insertion operation in a hash table that employs a list head for collision management?

O(1)

O(n)

O(log n)

O(n log n)

5. How efficient is the search operation in a hash table that uses a list head for handling collisions?

O(1)

O(n)

O(log n)

O(n log n)

6. How efficient is the delete operation in a hash table that employs a list head for collision resolution?

O(1)

O(n)

O(log n)

O(n log n)

7. Can a hash table reach full capacity when using open addressing?

Yes

Only if the load factor exceeds a certain threshold

Only if the hash function is not well-designed

8. What is the benefit of using a singly linked list instead of a doubly linked list for chaining?

It uses less memory

It leads to more collisions

It speeds up insertion and deletion

It results in fewer collisions

9. What is the maximum time complexity for inserting an element into a hash table that employs a list head for chaining?

O(1)

O(n log n)

O(log n)

O(n)

10. Which method is used to manage collisions in a hash table?

Open addressing

Hash function

Chaining

Rehashing

11. Does employing separate chaining with a list head effectively reduce collisions in a hash table?

Yes

Only if combined with a high-quality hash function

Only if the hash table is sufficiently large

12. What is a key benefit of using open addressing compared to separate chaining in hash tables?

Simpler to implement

The table never fills up

Less dependent on the hash function

Superior cache performance
