Lecture 29 | Infix to Prefix Conversion | DSA Practice

Welcome to Lecture 29 – Infix to Prefix Conversion In this lecture, we learn how to convert Infix expressions to Prefix (Polish Notation) using stack-based techniques. We break down the algorithm step-by-step and understand the role of operator precedence, associativity, and expression reversal. 💡 Topics Covered: -What is Infix, Prefix & Postfix -Why Prefix Notation is Useful -Steps to Convert Infix to Prefix -Reversing Expression Logic -Operator Precedence & Associativity -Stack-Based Implementation -Step-by-Step Dry Run -Handling Parentheses -Edge Cases Handling -Time & Space Complexity -Java Implementation 🎯 By the end of this lecture, you will be able to convert infix expressions to prefix efficiently and strengthen your stack concepts. 📌 Follow & Connect with Us: 📝 Registration link : https://forms.gle/QkGwatVBXDr6dpxi6 📸 Instagram: https://instagram.com/leetverse ✨ Keep practicing with LeetVerse — Learn, Code, Grow! #DSA #Stack #InfixToPrefix #DataStructures #Java #CodingPractice #LeetVerse #TechStudents
