A Stack can be implemented by using both ________ and ________.OptionsArrays, Linked listQueues, TreesGraph, Linked ListQueue, Graph

Question Analysis

The question asks about the two data structures that can be used to implement a Stack. A Stack is a Last In, First Out (LIFO) data structure, meaning that the last element added to the stack is the first one to be removed.

Answering the Options

1. Arrays: Yes, a Stack can be implemented using an array. Elements can be pushed onto and popped from the end of the array, maintaining the LIFO order.
2. Linked List: Yes, a Stack can also be implemented using a linked list. Each new element is added to the head of the list, allowing easy access to the last added element.

Other Options:

• Queues: A Queue operates on a First In, First Out (FIFO) basis, and therefore it cannot directly implement a Stack.
• Trees: A tree structure does not align with the LIFO behavior of a Stack.
• Graphs: Graphs are complex data structures that do not relate to the LIFO principle of a Stack.

Final Answer

A Stack can be implemented by using both Arrays and Linked Lists.
