The only difference is that we need to iterate the elements of arr[] in non-increasing order. Compute the sum of the maximum element of each subset, and the sum of the minimum element of each subset separately, and then subtract the minimum sum from the maximum to get the answer. But as we have to iterate through all subsets the time complexity for this approach is exponential O(n2^n). Subsets containing element a1: These subsets can be obtained by taking any subset of {a2,a3,, an} and then adding a1 into it. Taking reference of answer of Bhaskar13 https://stackoverflow.com/a/59386801/3509609 , I solved it without using the bit shift operators, to add more readability.
