🚀 Welcome to Part 88 of Code & Debug’s DSA in Python Course! In this video, we solve Leetcode 20: Valid Parentheses, a classic problem where we use a Stack to check whether the given expression has balanced brackets. This is one of the most frequently asked questions in coding interviews. 📚 What you’ll learn in this video: ✅ Understanding the problem statement and input constraints ✅ Using a stack to track opening and closing brackets ✅ Efficient way to handle multiple types of brackets – (), {}, [] ✅ Time and space complexity breakdown ✅ Common mistakes and edge case handling 💡 Why is this important? This problem strengthens your grasp on stack usage for syntax validation, which is widely used in compilers, expression parsing, and HTML/XML validation. It's a must-know for beginners and interview preparation. 👉 Practice the problem on Leetcode: 🔗 https://leetcode.com/problems/valid-parentheses/ 👉 Refer to the article for better understanding: 📌 https://codeanddebug.in/blog/valid-parentheses/ 👉 📄 Access the full YouTube DSA Playlist Sheet (All Questions in Order): 🔗 https://docs.google.com/spreadsheets/d/1AWE15Fy3wD2iqu2vjK_R7cCiuvSsjYQclcdZmHpF66o/edit?usp=sharing 👉 Enroll in the free DSA Python course here: https://codeanddebug.in/course/master-dsa-with-leetcode 👉 Enroll for Self-Paced Advance DSA course here: https://codeanddebug.in/course/zero-to-hero-python-dsa 🙏 Thank you for supporting Code & Debug!
