Questions & Step-by-Step Solutions

Which data structure would you use to implement a function call stack?
  • Step 1: Understand what a function call stack is. It keeps track of function calls in a program.
  • Step 2: Learn about the LIFO principle. LIFO stands for 'Last In, First Out', meaning the last item added is the first one to be removed.
  • Step 3: Realize that when a function is called, it is added to the top of the stack.
  • Step 4: When a function finishes executing, it is removed from the top of the stack.
  • Step 5: Conclude that a stack data structure is perfect for this because it naturally follows the LIFO principle.
