Lecture 30 | Prefix Expression Evaluation | DSA Practice

Welcome to Lecture 30 – Prefix Expression Evaluation In this lecture, we learn how to evaluate Prefix expressions (Polish Notation) using stack-based techniques. We break down the evaluation process step-by-step and implement an efficient solution by traversing the expression from right to left. 💡 Topics Covered: -What is Prefix Expression -Why Prefix Evaluation Works -Right-to-Left Traversal Logic -Stack-Based Evaluation Algorithm -Handling Operators & Operands -Step-by-Step Dry Run -Edge Cases Handling -Time & Space Complexity -Java Implementation 🎯 By the end of this lecture, you will be able to evaluate prefix expressions efficiently and strengthen your understanding of stack applications. 📌 Follow & Connect with Us: 📝 Registration link : https://forms.gle/QkGwatVBXDr6dpxi6 📸 Instagram: https://instagram.com/leetverse ✨ Keep practicing with LeetVerse — Learn, Code, Grow! #DSA #Stack #Prefix #DataStructures #Java #CodingPractice #LeetVerse #TechStudents
