This problem asks you to find the largest sum of a contiguous subarray within a given array of integers. For example, given the array [-2, 1, -3, 4, - 1, 2, 1, -5, 4], the largest sum of a contiguous subarray would be 6 (4 + -1 + 2 + 1 = 6).
A.I. Evaluation of the Solution
The candidate's solution is correct and solves the problem. The candidate's approach is also optimal, as they only iterate through the array once.
