Question 1

Question 1Assertion (A): The major implementation of using a data structure is to manage the storage of data in the memory efficiently.Reasoning (R): Data structure refers to the way memory is allocated for holding data using minimum space. It leads to faster data access during the execution of the program.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

Both A and R are true and R is the correct explanation of A.ExplanationData structures play a crucial role in efficiently managing data in memory. A data structure refers to the method of allocating memory to hold data using minimal space, which ensures faster data access during program execution.

Question 2

Question 2Assertion (A): While working with Stacks, the program should check for Overflow condition before executing push operation and, similarly, check for Underflow before executing pop operation.Reasoning (R): In Stack, Underflow means there is no element available to remove and Overflow means no further element can be added to it.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

Both A and R are true and R is the correct explanation of A.ExplanationTo use a Stack efficiently, it's crucial to check its status by examining overflow conditions before executing a push operation and underflow conditions before executing a pop operation. In a stack, underflow occurs when there are no elements available to remove (e.g., trying to pop from an empty stack), while overflow happens when there's no more space to add elements (e.g., trying to push onto a full stack).

Question 3

Question 3Assertion (A): Stack is a memory structure that works on the principle of FIFO (First In, First Out).Reasoning (R): Stack is implemented using list and allows to add an element using append() method.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is false but R is true.ExplanationA stack is a memory structure that works on the principle of LIFO (Last In, First Out), meaning that the last element added to the stack is the first one to be removed. In Python, a stack can be implemented using a list data structure, and the "append()" method is used to add elements to the top of the stack.

Question 4

Question 4Assertion (A): A Stack is a linear data structure that stores the elements in First In, First Out order.Reasoning (R): In Stack, a new element is added and removed from one end only.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is false but R is true.ExplanationA stack is a linear data structure that stores elements in LIFO (Last In, First Out) order, where the last element added to the stack is the first one to be removed. In a stack, a new element is added and removed from only one end, which is the top of the stack.

Question 5

Question 5Assertion (A): Stack and Queue are linear data structures.Reasoning (R): List, tuples and dictionaries are Python built-in linear data structures.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is true but R is false.ExplanationStacks and queues are linear data structures because they organize data elements in a linear order, allowing elements to be accessed in a sequential manner. Python provides built-in data structures like lists, tuples, and dictionaries. Lists and tuples are examples of linear data structures as they store elements in a specific linear order, while dictionaries are non-linear data structures because they do not maintain a specific linear order, and elements are accessed based on their keys rather than indices.

Question 6

Question 6Assertion (A): An element in a Stack is removed from its Top.Reasoning (R): The process of removing an element from a Stack is called pop.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

Both A and R are true and R is the correct explanation of A.ExplanationAn element in a stack is removed from its top. The stack follows the Last-In-First-Out (LIFO) approach, where the last element added (the top element) is the first one to be removed. The process of removing an element from a stack is called pop.

Question 7

Question 7Assertion (A): An error gets displayed when you try to delete an element from an empty Stack.Reasoning (R): Inserting an element when the Stack is full is termed as Underflow.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.A is true but R is false.A is false but R is true.

Accepted Answer

A is true but R is false.ExplanationWhen we attempt to delete an element from an empty stack, it results in an error known as an underflow error. This occurs because the stack is empty, and there's no element to remove. On the other hand, inserting an element when the stack is full is termed as an overflow condition.
