Explanation: Possible partitions are: {2, 4, 6} Approach: The idea is to observe that if there is no such pair i, j such that |arr [i] - arr [j]| = 1, then it is possible to put all the elements in the same partition, otherwise divide them into two partitions. 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. The task is to find the greatest difference between the sum of m elements in an array. The minimum difference between 2 sets is 1 Time Complexity = O (n*sum) where n is number of elements and sum is sum of all elements. Note: The subsets cannot any common element. Note that another optimal solution is to partition nums into the two subsequences [1] and [2,3]. Agree Lets now understand what we have to do using an example .

Maximum possible difference of two subsets of an array in C++ C++ Server Side Programming Programming In this tutorial, we will be discussing a program to find maximum possible difference of two subsets of an array For this we will be provided with an array containing one or two instances of few random integers. So, we can easily ignore them. Input: arr [] = {2, 7, 4, 1, 6, 9, 5, 3} Output: 4 Recommended: Please try your approach on {IDE} first, before moving on to the solution. To partition nums, put each element of nums into one of the two arrays. 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. Hence, the sum of the minimum element of all subsets will be:min_sum = a1*2n-1 + a2*2n-2 + + an*20This sum can be computed easily in linear time with help of the Horner methodSimilarly, we can compute the sum of the maximum element of all subsets of arr[].
