n = Given a non-empty array arr with n integers both positive and negative, find the maximum sum of a contiguous subarray within arr. def solutionA(arr): len(arr) max_so_far = arr[] for i in range(n): for j in range(i, n): sum for k in range(i, j + 1): sum += arr[k] if sum > max_so_far: max so far = sum return max_so_far What is the runtime of this solution (using big-O notation)?
