Trapping Rain Water (LeetCode 42) Visualized in 30s #leetcode #datastructures

LeetCode 42: Trapping Rain Water is one of the most frequently asked FAANG coding interview questions. But how do you solve it without running out of memory? 🌊

In this video, we visualize the optimal Two Pointers approach to solve Trapping Rain Water in O(N) Time and O(1) Space. Instead of using extra arrays to store the left and right max heights, we move the pointer with the shorter wall inward, calculating the trapped water on the fly!

Mastering this algorithm is essential for Data Structures and Algorithms (DSA) rounds at Google, Meta, and Amazon.
