Description

[Hunterdii]

Thank you for your contribution! However, the current PR does not follow the required format and lacks an optimized implementation. Please make the following changes:

1. Follow the proper README format as mentioned in the repository. The README should include:

   • A detailed problem description
   • Examples with explanations
   • Constraints
   • A well-explained approach
   • Optimized code in C++, Java, and Python
   • A comparison table for different approaches

2. Optimize the code: The current implementation needs improvements in both time and space complexity. Please provide the most efficient solution and avoid redundant operations.

3. Structure the submission properly: Ensure that the README is well-formatted and the code is comment-free while maintaining clarity. (See Below Format Follow the Same)
