In this video, I walk through how to solve the Valid Parentheses coding problem step by step using a stack data structure in Java.
This is a beginner-friendly explanation where we go slowly through the logic so you can truly understand why the solution works — not just memorise it.
We cover:
✅ What the problem is asking
✅ Why a stack is the perfect data structure
✅ Step-by-step code walkthrough
✅ How matching brackets work
✅ Edge cases (like "(((")
✅ Time and space complexity
If you're learning data structures, preparing for coding interviews, or practicing LeetCode problems — this video will help you build strong problem-solving skills.
