🚀 Welcome to Part 90 of Code & Debug’s DSA in Python Course!

In this lecture, we cover an important theoretical + practical concept — Infix, Postfix, and Prefix expressions, and how to convert between them using stacks. These notations are heavily used in expression evaluation, compiler design, and interview problems.

📚 What you’ll learn in this video:
✅ What are Infix, Postfix, and Prefix expressions
✅ Why we use Postfix/Prefix over Infix in computation
✅ Conversion techniques:
 • Infix to Postfix
 • Infix to Prefix
 • other conversions
✅ Stack-based implementation logic
✅ Order of precedence, associativity, and parentheses handling

💡 Why is this important?
This topic is frequently asked in interviews and entrance exams, and is foundational for understanding how programming languages, compilers, and calculators evaluate expressions internally.
