Hustle & Code – Day 3/25 🔥 Polymorphism in Java + LeetCode Strings + Backend Configuration & Routes

🚀 Day 3 of my 25-Day Coding Challenge completed!
Today I dived deeper into OOP concepts in Java (Inheritance & Polymorphism), solved LeetCode String problems (Valid Anagram & Valid Palindrome), and upgraded my backend skills by creating an API with route and configuration 🙌.

In this series, I’m documenting my journey of:
✅ Java + DSA preparation for placements
✅ LeetCode problem-solving (Easy to Medium)
✅ Step-by-step Backend Development (Node.js + APIs)
✅ Daily YouTube Shorts & Instagram Reels updates

This challenge is all about consistency, problem-solving, and leveling up as a developer 💻🔥.

👉 Stay tuned for more — Day 4 drops tomorrow! 🚀
