Anand won the #code-crunch on his second attempt! Anand had the best answer to the code-crunch on:
The input array representing a building blocks where the width of each block is 1, calculate how much water we can store in between the blocks.
Example 1: arr[] = [3, 1, 0,2]
Output: 3
Structure is like below:
