1. Maximum Subarray Sum

Asked in companies
You are given an array 'arr' of length 'n', consisting of integers.
A subarray is a contiguous segment of an array. In other words, a subarray can be formed by removing 0 or more integers from the beginning and 0 or more integers from the end of an array.
Find the sum of the subarray (including empty subarray) having maximum sum among all subarrays.
The sum of an empty subarray is 0.
Example :
Input: 'arr' = [1, 2, 7, -4, 3, 2, -10, 9, 1]
Output: 11
Explanation: The subarray yielding the maximum sum is [1, 2, 7, -4, 3, 2].
Problem approach
Divide the array into 2 halves.
Get the answer of left and right parts of the array by recursion.
Get the answer of Maximum subarray sum such that the subarray crosses the midpoint.
To find the maximum subarray sum of crossing points we need to find the maximum sum starting from mid point and ending at some point on the left of mid, then find the maximum sum starting from mid + 1 and ending with some point on right of mid + 1. Total sum would be the sum of both left part and right part.
Maximum of all three sums would be the final answer.
