Two pointers | Brute force and Optimised Solution discussed
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.
