Question: Which of the following statements about stacks is true?

Options:

  1. Stacks can be implemented using arrays or linked lists.
  2. Stacks allow random access to elements.
  3. Stacks are FIFO data structures.
  4. Stacks can only store integers.

Correct Answer: Stacks can be implemented using arrays or linked lists.

Solution:

Stacks can indeed be implemented using both arrays and linked lists, while they follow LIFO (Last In, First Out) order.

  2. Stacks allow random access to elements.
  3. Stacks are FIFO data structures.
  4. Stacks can only store integers.

Questions & Step-by-Step Solutions

Which of the following statements about stacks is true?
  • Step 1: Understand what a stack is. A stack is a data structure that stores items in a specific order.
  • Step 2: Learn about the order of a stack. Stacks follow the LIFO principle, which means the last item added is the first one to be removed.
  • Step 3: Know how stacks can be created. Stacks can be implemented using two main methods: arrays and linked lists.
  • Step 4: Recognize that both methods allow for the same LIFO behavior, meaning they both work the same way in terms of adding and removing items.
