What is the approach for solving GSS1 and GSS3 on SPOJ using segment trees?
What is the difference between GSS1 and GSS3?
GSS1 asks you to find the maximum sum of a contiguous subarray in a given array. On the other hand, GSS3 asks you to find the maximum sum of two non-overlapping contiguous subarrays in a given array.
