Data Structures: Stacks and Queues

 Data Structures: Stacks and Queues in C++

Stacks and Queues are the foundational building blocks of algorithmic efficiency. They provide deterministic ways to manage data flow: Stacks follow the LIFO (Last In, First Out) principle, while Queues operate on FIFO (First In, First Out). Mastery of these structures in C++ is critical for memory management, task scheduling, and compiler design.

In this module, you will transition from basic array-based containers to advanced computational simulations, such as Reverse Polish Notation (RPN) and circular memory buffers.

Core Technical Domains

  • LIFO logic: Push, Pop, and Peek.
  • FIFO logic: Enqueue and Dequeue.
  • Parsing: Infix to Postfix conversion.
  • Circular Buffers: Memory optimization.
  • Simulation: Scheduling & Spooling.
  • Stack Recursion: Iterative factorials.

Data Structures Challenges

Data Structure Challenge Implementation Objective
Basic Stack (LIFO) Build a stack from scratch using static or dynamic arrays to master Push/Pop mechanics.
Basic Queue (FIFO) Implement a linear buffer to process data in strict arrival order.
Infix to Postfix Utilize a stack to convert mathematical notations into machine-readable postfix strings.
Balanced Parentheses Develop a syntax validator using stack-based character matching logic.
Print Queue Simulation Model real-world spooling systems where print jobs are handled sequentially.
Evaluate Postfix Calculate numerical results from RPN notation using an intermediate stack.
Circular Queue Optimize memory usage by implementing a wrap-around buffer logic.
Logical Expressions Process complex Boolean operations (AND, OR, NOT) via stack traversal.
Bank Queue System Design a customer flow model with arrival timestamps and service logic.
Factorial via Stack Simulate recursion using an explicit stack to manage memory and states.
