Array Sum Challenge
In this challenge, given an array of integers, the goal is to efficiently
find
the start and end indices of the subarray that has the greatest value when
all
of its elements are summed together. Note that because some elements of the
array may be negative, the problem is not solved by simply returning the
start
and end elements of the array.
{1, 2, -5, 4, -3, 2}
The maximum sum of a subarray is 4.
Before you write the code, take some time to think of the most efficient solution possible; it may surprise you. The major goal of this challenge is to test your algorithmic skills rather than merely your ability to write code quickly.
