For making the difference of the sum of elements of both subset maximum we have to make subset in such a way that all positive elements belong to one subset and negative ones to other subsets. Here also, we need to ignore those elements that come several times or more than once. Note sort(arr[],int) is assumed to return the sorted array. For example, Consider the array [1, 2, 3, 4], There are 10 non-empty sub-arrays. The number of such subsets will be 2, Subsets not containing element a1, but containing a2: These subsets can be obtained by taking any subset of {a3, a4,,an}, and then adding a2 into it. Input .

Given an array of n-integers. This is a recursive method in which we consider each possible subset of the array and check if its sum is equal to total sum S/2 or not, by eliminating the last element in the array in each turn. The only difference is that we need to iterate the elements of arr[] in non-increasing order. Our task is to create two subsets of that array such that the difference of their sum is maximum and no subset contains repetitive numbers. Agree Subsets need not be contiguous always. Maximum number of subsets an array can be split into such that product of their minimums with size of subsets is at least K - GeeksforGeeks A Computer Science portal for geeks.
