JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - LeetCode Example Solution - Trapping Rainwater

The video tutorial explains how to write a function to calculate the maximum amount of rainwater that can be trapped between bars of different heights. It covers setting up the function, iterating through the array to calculate max left and max right values, and using these to determine the trapped water. The tutorial includes detailed logging and debugging steps to help understand the process, culminating in a solution verification.

Describe how the algorithm iterates through the array to calculate trapped rainwater.

What is the significance of the variable 'X-plane graph' in the context of the algorithm?

How does the algorithm ensure that it does not exceed the bounds of the array?

What is the purpose of using 'Math.max' in the algorithm?
