 Maximum subarray problem

Given a finite sequence of real numbers, find a nonempty contiguous block with maximum sum. Its restriction to contiguous blocks distinguishes it from choosing an arbitrary subset. The problem admits a linear-time solution using Kadane's algorithm.

The Maximum Subarray Problem is a classic algorithmic problem that involves finding the contiguous subarray within a one-dimensional array of numbers that has the largest sum. In other words, given an array of integers (which can include both positive and negative numbers), the goal is to identify the subarray (a contiguous segment of the array) that yields the highest possible sum.
