Improve documentation for BinarySearch implementation #7327
Description
What would you like to share?
The BinarySearch implementation works correctly, but adding more detailed comments and usage examples would help beginners understand the algorithm better.
Suggested improvements:
- Add step-by-step explanation of how binary search narrows down the search space
- Include a simple example input/output
- Mention time complexity (O(log n)) clearly in comments
This will improve readability and learning experience for new contributors.
