Hey Everyone!

What Are Stacks?
A stack is a linear data structure that operates on the principle of Last In, First Out (LIFO). Imagine a stack of plates: the last plate you place on top is the first one you remove.

Core Operations:

  • Push: Add an element to the top of the stack.
  • Pop: Remove the top element.
  • Peek/Top: View the top element without removing it.

When to Use Stacks:

  1. Recursion Management: Function calls are stored in a stack, allowing the system to keep track of where it left off.
  2. Expression Parsing: Stacks evaluate mathematical expressions or handle parentheses matching.
  3. Undo Features: Actions are stored on a stack to enable step-by-step reversal.

Limitations of Stacks:

  • Limited access: You can only access the top of the stack directly.
  • Fixed size in static implementations (like arrays).

Real-World Applications:

  • Browser history navigation (back and forward actions).
  • Tracking previous states in applications.

This is a solid explanation of stacks in data structures and their practical applications! Stacks are incredibly useful in various fields, especially for things like managing recursive function calls, expression evaluation, and undo operations in software.

Have you worked with stacks in any of your projects or coursework? How have you applied them?

No, I haven’t worked with stacks in my projects or coursework, but I know they are crucial in areas like managing recursive function calls, evaluating mathematical expressions, and enabling undo/redo functionality in software.
