What are the differences between an array and a stack?

Skill Assessed
  • 1. Data structures knowledge : Understanding of the fundamental properties and operations of arrays and stacks.

  • 2. Memory management : Awareness of how each structure handles memory allocation and deallocation.

  • 3. Complexity analysis : Ability to compare the time and space complexity of operations performed on arrays and stacks.

  • 4. Practical application : Recognizing real-world scenarios where one would be preferred over the other.

Purpose
  • 1. Analytical thinking : Evaluating your ability to critically differentiate between two commonly used data structures.

  • 2. Technical knowledge : Assessing your understanding of basic data structures and algorithms.

  • 3. Problem-solving skills : Gauging your competence in choosing the appropriate data structure for a given problem.

  • 4. Communication skills : Observing your ability to clearly and concisely explain technical concepts.


Hints
  • 1. FIFO/LIFO : Remember that stacks operate on a Last In, First Out (LIFO) principle, which might guide your discussion on the nature of their operations.

  • 2. Indexing : Consider bringing up whether or not the structure supports direct indexing to elements.

  • 3. Use cases : You might want to mention typical use cases for each, such as navigating browser history for stacks, and managing a collection of items in a fixed order for arrays.
