We are going to store it in the map (making it a positive number) with its number of occurrences. We can optimize the above solution using more efficient approaches discussed in below post. Given an array, you have to find the max possible two equal sum, you can exclude elements. You have to make two subsets such that the difference of the sum of their elements is maximum and both of them jointly contain all elements of the given array along with the most important condition, no subset should contain repetitive elements. Note, this is the maximum difference possible. 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. 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. So the required minimum number of partitions is always 1 or 2. After getting the sum of all positive and negative elements condition followed that elements having frequency 1 only, we need to return the difference of both the sums and that would be our answer. Given an array S of N positive integers, divide the array into two subsets such that the sums of subsets is maximum and equal. Contribute to apachecn/geeksforgeeks-dsal-zh development by creating an account on GitHub. The only difference is that we need to iterate the elements of arr[] in non-increasing order. A Computer Science portal for geeks. Input: arr[] = {1, -5, 3, 2, -7}Output: 18Explanation: The partitions {1, 3, 2} and {-5, -7} maximizes the difference between the subsets. Here we will first sort the elements of array arr[]. Finally return difference between two sums. Approach: The maximum absolute difference in the array will always be the absolute difference between the minimum and the maximum element from the array. You should make two subsets so that the difference between the sum of their respective elements is maximum. Before solving this question we have to take care of some given conditions, and they are listed as: Time Complexity O(n2)Auxiliary Space: O(1). So the highest or maximum difference is 12-6 which is 6. I have to divide the array into two subset such that one subset has exactly M elements and the other subset has the rest.
