Description of Change
Refactored the implementation of the Trapped Rainwater problem to use the two-pointer approach, reducing the space complexity from O(n) to O(1) while maintaining O(n) time complexity. This improves efficiency and aligns with optimal algorithmic practices. The Doxygen-style documentation and metadata were also updated to reflect the change in logic and complexity.
Checklist
Notes: Optimized the Trapped Rainwater solution using a two-pointer technique to improve space efficiency without sacrificing readability or correctness. Suitable for competitive programming and educational references. Fixes #2975
