Which data structure would you use to implement a call stack?
Step 1: Understand what a call stack is. A call stack keeps track of function calls in a program.
Step 2: Learn about the stack data structure. A stack is a collection of items that follows the Last In, First Out (LIFO) principle.
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 the best choice for implementing a call stack because it matches the way functions are called and returned.
