What is the primary operation of a heap data structure?

• Insertion

• Deletion

• Searching

• Sorting

Which data structure allows elements to be accessed in a sequential manner only?

• Queue

• Stack

• Linked List

• Tree

What data structure does a depth-first search (DFS) typically utilize?

• Queue

• Stack

• Linked List

• Hash Table

Which data structure is used to implement Dijkstra's shortest path algorithm?

• Stack

• Queue

• Heap

• Linked List

What is the main disadvantage of using an array compared to a linked list for insertion and deletion operations?

• Arrays have limited size

• Arrays require more memory

• Arrays have slower access time

• Arrays have fixed size

What is the primary purpose of a stack data structure?

• FIFO (First In, First Out) access

• LIFO (Last In, First Out) access

• Random access

• Priority access

Which data structure is used to represent a hierarchical structure with a root value and sub-values?

• Array

• Queue

• Tree

• Linked List

What is the time complexity of searching for an element in a binary search tree (BST)?

• O(1)

• O(log n)

• O(n)

• O(n^2)

Which operation is typically NOT supported by a stack?

• Push

• Pop

• Peek

• Insert

What is the primary advantage of using a hash table for data storage?

• Constant time complexity for all operations

• Efficient sorting capabilities

• Easy implementation of linked structures

• Guaranteed order of elements
