In this video, we deep dive into the Two Pointers technique, starting from the brute force approach and then optimizing it step by step.
You’ll understand:
What the two pointers technique is
How the brute force solution works and why it’s inefficient
How to optimize the solution using two pointers
Time and space complexity comparison
When and where to apply two pointers in real DSA problems
This approach is widely used in problems related to:
Arrays and strings
Searching pairs
Sorting-based problems
Interview and competitive programming questions
Perfect for beginners and intermediate learners preparing for coding interviews, DSA, and placements.
📌 Watch till the end to clearly understand the transition from brute force → optimized solution.
