Which searching algorithm is most efficient for finding an element in a sorted array?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Jump Search


Correct Option: B
Explanation:

Binary Search is the most efficient algorithm for finding an element in a sorted array because it uses the divide-and-conquer approach to narrow down the search space quickly.

What is the worst-case time complexity of Linear Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: C
Explanation:

Linear Search has a worst-case time complexity of O(n) because it needs to examine each element of the array sequentially.

Which searching algorithm is suitable for finding an element in a nearly sorted array?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Jump Search


Correct Option: C
Explanation:

Interpolation Search is suitable for finding an element in a nearly sorted array because it uses a formula to estimate the position of the element based on its value.

What is the average-case time complexity of Binary Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: B
Explanation:

Binary Search has an average-case time complexity of O(log n) because it repeatedly divides the search space in half until the element is found.

Which searching algorithm is best suited for finding an element in a large, unsorted array?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Jump Search


Correct Option: D
Explanation:

Jump Search is best suited for finding an element in a large, unsorted array because it uses a skipping technique to quickly narrow down the search space.

What is the worst-case time complexity of Jump Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: C
Explanation:

Jump Search has a worst-case time complexity of O(n) because it needs to examine every element of the array in the worst case.

Which searching algorithm is most suitable for finding an element in a hash table?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Hashing


Correct Option: D
Explanation:

Hashing is the most suitable algorithm for finding an element in a hash table because it uses a hash function to directly compute the location of the element in the table.

What is the worst-case time complexity of Hashing?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: A
Explanation:

Hashing has a worst-case time complexity of O(1) because it directly computes the location of the element in the hash table using a hash function.

Which searching algorithm is used in a self-balancing binary search tree?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. AVL Tree Search


Correct Option: D
Explanation:

AVL Tree Search is used in a self-balancing binary search tree to efficiently find an element while maintaining the balance of the tree.

What is the worst-case time complexity of AVL Tree Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: B
Explanation:

AVL Tree Search has a worst-case time complexity of O(log n) because it efficiently traverses the balanced binary search tree to find the element.

Which searching algorithm is used in a B-tree?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. B-Tree Search


Correct Option: D
Explanation:

B-Tree Search is used in a B-tree to efficiently find an element while maintaining the structure and balance of the tree.

What is the worst-case time complexity of B-Tree Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: B
Explanation:

B-Tree Search has a worst-case time complexity of O(log n) because it efficiently traverses the balanced B-tree to find the element.

Which searching algorithm is used in a skip list?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Skip List Search


Correct Option: D
Explanation:

Skip List Search is used in a skip list to efficiently find an element while maintaining the structure and balance of the list.

What is the worst-case time complexity of Skip List Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: B
Explanation:

Skip List Search has a worst-case time complexity of O(log n) because it efficiently traverses the balanced skip list to find the element.

Which searching algorithm is used in a bloom filter?

  1. Linear Search

  2. Binary Search

  3. Interpolation Search

  4. Bloom Filter Search


Correct Option: D
Explanation:

Bloom Filter Search is used in a bloom filter to efficiently check if an element is present in the filter.

What is the worst-case time complexity of Bloom Filter Search?

  1. O(1)

  2. O(log n)

  3. O(n)

  4. O(n^2)


Correct Option: A
Explanation:

Bloom Filter Search has a worst-case time complexity of O(1) because it directly checks if an element is present in the filter using a hash function.
