Trapping Rainwater Problem – Brute Force and Optimized Two-Pointer Approach Explained

In this video, I have explained the Trapping Rainwater problem step by step, starting from the brute force approach and then moving to the optimized two pointer solution. First, we understand the intuition behind the problem and how water gets trapped between bars. Then we solve it using the brute force method and analyze its time complexity. After that, we optimize the solution using the two pointer approach to reduce the time and space complexity. In this video you will learn: How to think about left max and right max Why brute force works but is inefficient How to optimize the solution How two pointers help in solving it in linear time Important pattern for coding interviews This is a very important problem for coding interviews and helps you understand array patterns deeply.
