Maximum Sum Subarray Problem Statement

Given an array ARR consisting of N integers, determine the sum of the subarray with the maximum sum, including the possibility of an empty subarray.

A subarray is a contiguous portion of an array and can range from fully (including zero or more elements removed from each end) to partially inclusive of the original array.

Example:

Input:

N = 5
ARR = [-2, 1, -3, 4, -1]

Output:

4

Explanation:

The largest sum subarray is [4] which would give a sum of 4.

Constraints:

1

Explanation:

The largest sum subarray is [4] which would give a sum of 4.

Constraints:

1 <= N <= 10^6
-10^6 <= ARR[i] <= 10^6
Time limit: 1 second

Accepted Answer

Find the sum of the subarray with the maximum sum in a given array.

Iterate through the array and keep track of the current sum and maximum sum.
Update the maximum sum if the current sum becomes greater.
Handle cases where the array has all negative numbers or empty subarray.
Example: For input [-2, 1, -3, 4, -1], the maximum sum subarray is [4] with sum 4.
