Khxshx commented 1 year ago

Given an array of N non-negative integers arr[] representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining.

Examples:

Input: arr[] = {2, 0, 2} Output: 2 Explanation: The structure is like below. Untitled-Diagram711

We can trap 2 units of water in the middle gap.

Input: arr[] = {3, 0, 2, 0, 4} Output: 7

Explanation: Structure is like below. Untitled-Diagram811

We can trap “3 units” of water between 3 and 2, “1 unit” on top of bar 2 and “3 units” between 2 and 4.
