Optimize Trapping Rain Water
Problem Description
You are given an n length array of non-negative integers, height, representing an elevation map where the width of each bar is 1. Your task is to compute how much water it can trap after raining.
Requirements
- Implement a brute-force solution to calculate the trapped rainwater.
- Analyze the time and space complexity of the brute-force solution.
- Develop an optimized solution that achieves O(n) time complexity and O(n) space complexity.
- Discuss potential approaches and considerations for further optimizing the solution to achieve O(1) space complexity.
