Data Structures & Algorithms Quiz


Froggy Jumps Data Structures & Algorithms QuizOnline version Test your knowledge on fundamental data structures and algorithms! by Artemis Rose 1 What is a pointer in programming? a A variable that stores a fixed value. b A variable that stores a memory address of another variable. c A function that points to other functions. 2 What does a linked list consist of? a Nodes containing data and a pointer to the next node. b A sequence of fixed-size arrays. c A collection of unrelated variables. 3 What is the main purpose of a queue? a To store data in a hierarchical manner. b To follow FIFO (First In First Out) order. c To access data randomly. 4 Which operation inserts an element at the rear of a queue? a Enqueue (Push) b Dequeue (Pop) c Peek 5 What is an Abstract Data Type (ADT)? a A specific data structure like array or linked list. b A programming language feature. c A model defining operations without implementation details. 6 What does Big O notation describe? a The efficiency of an algorithm in time or space. b The size of the input data. c The number of operations performed. 7 Which operation is used to modify an element in an array? a Updation b Traversal c Searching 8 What is the purpose of the linear search algorithm? a To find an element by checking each element sequentially. b To insert an element efficiently. c To sort the array. 9 In a stack, what does the pop operation do? a Displays the entire stack. b Adds an element at the bottom. c Removes the top element. 10 What is the primary characteristic of a static data structure? a Fixed memory size. b Memory allocated at runtime. c Memory size varies dynamically. 11 What does a pointer do in programming? a Stores the value directly b Handles input/output operations c Stores the memory address of a variable 12 What is a data structure? a A type of programming language b A hardware component c A way of organizing and storing data efficiently 13 What is a linked list? a A sorting algorithm b A linear data structure with nodes containing data and pointers c A type of array 14 What does FIFO mean in a queue? a First In Last Out b First In First Out c Fast Input Output 15 What is the purpose of the 'pop' operation in a stack? a Add a new element b Check the size c Remove the top element 16 What is an Abstract Data Type (ADT)? a A programming language b A model with defined operations but no implementation c A specific data structure 17 What does algorithm complexity measure? a Efficiency in time and space resources b Ease of understanding c Number of steps 18 Which operation is NOT typically performed on arrays? a Traversal b Sorting c Insertion 19 What is the first step in a linear search algorithm? a Check the last element b Start from the first element c Sort the array 20 In a stack, what does the 'push' operation do? a Search for an element b Remove the top element c Add an element to the top 21 What does a pointer do in programming? a Stores a value directly b Stores the memory address of another variable c Performs arithmetic operations 22 How are data structures classified? a Numeric and non-numeric b Linear and non-linear, static and dynamic c Simple and complex 23 What is a linked list? a A type of array with fixed size b A data structure with only one node c A linear data structure where each node points to the next 24 What does a queue follow? a LIFO (Last In First Out) b FIFO (First In First Out) c Random access 25 Which operation inserts an element at the rear of a queue? a Peek b Dequeue (Pop) c Enqueue (Push) 26 What is an Abstract Data Type (ADT)? a A specific data structure like array or list b A model defining operations without implementation details c A programming language feature 27 What does algorithm complexity measure? a Ease of understanding b Number of steps only c Efficiency in time and space resources 28 Which operation is NOT performed on arrays? a Compilation b Insertion c Traversal 29 What is the first step in linear search? a Start from the first element and compare with the key b Sort the array c Insert the element at the end 30 What does the push operation do in a stack? a Adds an element to the top of the stack b Checks if the stack is empty c Removes the bottom element
