Given an array, you have to find the max possible two equal sum, you can exclude elements. Given an array arr[ ] consisting of N integers, the task is to find maximum difference between the sum of two subsets obtained by partitioning the array into any two non-empty subsets. This is still O(n log n) by the way. Affordable solution to train a team and make them project ready. The difference between the maximum and minimum value in the first subsequence is 2 - 1 = 1.

Note: We may have a large answer, so we have to calculate the answer with mod 10^9 +7. Consider both cases and take max. Suppose max (s) represents the maximum value in any subset 's' whereas min (s) represents the minimum value in the set 's'. Approach: The given problem can be solved with the help of the Greedy Approach using the Sliding Window Technique. Suppose we have an array and a number m, then we will first find the sum of highest m numbers and then subtract the sum of lowest m numbers from it to get the maximum difference. i.e 1,2,3,4,6 is given array we can have max two equal sum as 6+2 = 4+3+1.
