Maximum Subarray Sum Problem Statement

Given an array of integers, determine the maximum possible sum of any contiguous subarray within the array.

Example:

Input:

array = [34, -50, 42, 14, -5, 86]

Output:

137

Explanation:

The maximum sum is achieved by the subarray [42, 14, -5, 86].

Input:

array = [-5, -1, -8, -9]

Output:

-1

Explanation:

The maximum sum is -1, achieved by the subarray [-1].

Constraints:

1 ≤ N ≤ 10⁶, where N is the number of elements in the array.

-10⁴ ≤ array[i] ≤ 10⁴

Note:

The solution should have a time complexity of O(N).

Input:

The first line contains a single integer, N, the size of the array. The second line contains N space-separated integers representing the elements of the array.

Output:

A single integer, the maximum subarray sum.

Accepted Answer

Find the maximum sum of any contiguous subarray within an array of integers.

Iterate through the array and keep track of the maximum sum of subarrays encountered so far.
At each index, decide whether to include the current element in the subarray or start a new subarray.
Update the maximum sum if a new maximum is found.
Time complexity should be O(N) to iterate through the array once.
Example: For array [34, -50, 42, 14, -5, 86], the maximum subarray sum is 137.
