- Initialize `answer = 0`
- Iterate the array from left to right:
- Initialize `max_left = 0 and `max_right = 0`
- Initialize `max_left = 0` and `max_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]` to `answer`
