Welcome to srkcodes! In today’s Telugu coding tutorial, we solve Leetcode Question #392: Is Subsequence — a widely asked DSA problem that strengthens string manipulation and pointer-based logic.

In this video, we break down two powerful approaches:
1️⃣ Brute Force using a DFS-style helper function to manually explore subsequence possibilities.
2️⃣ Two Pointer Technique for a clean, optimal, interview-ready solution.

This session is perfect for anyone learning Python DSA in Telugu, preparing daily coding challenges, or aiming to improve algorithmic thinking. Each step is explained clearly so beginners and experienced learners can follow easily.

What you’ll gain:
• Strong understanding of subsequence logic
• Mastery of pointer movement and string traversal
• Ability to compare brute force and optimal approaches
• Improved confidence in solving Leetcode string problems

Drop your questions or alternate solutions in the comments — let’s grow together!
