Pre-Launch Promotion An element of array can store water if there are higher bars on left and right. We can find amount of water to be stored in every element by finding the heights of bars on left and right sides. The idea is to compute amount of water that can be stored in every element of array. For example, consider the array [3, 0, 0, 2, 0, 4], We can trap "3*2 units" of water between 3 an 2, "1 unit" on top of bar 2 and "3 units" between 2 and 4. See below diagram also. Instagram.

- Initialize
answer = 0 - Iterate the array from left to right:
- Initialize
max_left = 0andmax_right = 0 - Iterate from the current element to the beginning of array updating:
max_left = max(max_left, height[j]) - Iterate from the current element to the end of array updating:
max_right = max(max_right, height[j]) - Add
min(max_left, max_right) − height[i]toanswer
