Data Structures and Algorithms with Python | Free DSA with Python Course - DSA in Python Course - Infix, Postfix & Prefix | Conversions Explained with Stack - Part 90 [Hindi]

🚀 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. 👉 Link to solve the question: https://www.geeksforgeeks.org/problems/infix-to-postfix-1587115620/1 https://www.geeksforgeeks.org/problems/prefix-to-infix-conversion/1 https://www.geeksforgeeks.org/problems/prefix-to-postfix-conversion/1 https://www.geeksforgeeks.org/problems/postfix-to-prefix-conversion/1 https://www.geeksforgeeks.org/problems/postfix-to-infix-conversion/1 https://www.geeksforgeeks.org/problems/infix-to-postfix-1587115620/1 👉 In-Depth Article with Code & Explanations: https://codeanddebug.in/blog/infix-postfix-prefix-conversions-explained-in-python/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in this FREE DSA Python course here: 🔗 https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advanced DSA course here: 🔗 https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
