How do you find the maximum sum of an array?

Find the Maximum subarray sum using Kadane' Algorithm. Keep that subarray intact and multiply the rest with -1. Considering the sum of the whole array as S, and the largest sum contiguous subarray as S1, the total sum will be equal to -(S-S1) + S1 = 2*S1 – S. This is the required sum.Apr 21, 2021
