Optimized Implementation of Kadane's Algorithm for Maximum Subarray Sum in C++

[stutimi]

This C++ program utilizes Kadane's Algorithm to efficiently find the maximum sum of a contiguous subarray from a given array of integers. The implementation leverages built-in functions from the C++ Standard Library, such as std::max, for optimal performance and clarity. It utilizes std::vector for dynamic array handling, ensuring safety and reducing memory allocation issues. The program takes multiple test cases as input and processes each case to compute and output the maximum subarray sum. This solution operates in O(n) time complexity, making it ideal for handling large datasets in competitive programming contexts.
