Avoid Redundant Initialization

[Anshuman7080]

Avoid Redundant Initialization: Instead of initializing sum to 0 and resetting it when negative, we directly check if the current element alone is greater than the accumulated sum. Check for Empty Array: Added a condition to handle the case of an empty input array gracefully, returning 0 if no elements exist. Use of std::max: This ensures clarity and avoids potential pitfalls with type conversions. This version maintains the algorithm's efficiency while improving readability and robustness
