Improve null and edge case handling in BinarySearch implementation

[AbhiramSakha]

What would you like to share?

The current BinarySearch implementation does not explicitly handle certain edge cases such as null input arrays or null search values.

Suggested improvements:

• Add null check for the input array
• Handle empty array case
• Add null check for the search value to prevent potential NullPointerException

This will improve robustness and ensure safer usage of the algorithm.

I would like to work on this issue and submit a PR.
