Another problem solved and another step forward in my coding journey! 💻

Today, I successfully solved LeetCode Problem 9: Palindrome Number using JavaScript.

The challenge was to determine whether a given integer reads the same forward and backward.

For example:

✅ Input: 121 → Output: true

❌ Input: -121 → Output: false

❌ Input: 10 → Output: false

💡 My Approach

I used a mathematical approach to reverse the number without converting it into a string.

Here's how the logic works:

1. Handle negative numbers and numbers ending in zero (except zero itself).
2. Extract the last digit using the modulo operator (%).
3. Build the reversed number digit by digit.
4. Compare the original number with the reversed number.

If both numbers match, the input is a palindrome!

📚 What I Learned

This problem helped me strengthen my understanding of:

🔹 JavaScript mathematical operators

🔹 While loops and conditional statements

🔹 Number manipulation

🔹 Logical problem-solving

🔹 Writing efficient solutions with constant extra space

Every coding problem teaches something new. Even seemingly simple challenges help build the foundation for solving more complex algorithmic problems.

I'm continuing to practice Data Structures and Algorithms to improve my problem-solving skills and prepare for future opportunities in software development.

One problem at a time. One step closer to becoming a better developer! 🚀
