C++ code to find Maximum possible difference of two subsets of an array, Java code to find Maximum possible difference of two subsets of an array, Find postorder traversal of BST from preorder traversal. Why is subtracting these two times (in 1927) giving a strange result? You need to partition nums into two arrays of length n to minimize the absolute difference of the sums of the arrays. After storing the frequencies of the positive elements we are going to add up all the values of an array which are greater than 0 and also have a frequency of only 1, means we need to ignore those elements that come several times or more than once. Then we will find the sum of first m and last m elements as these will be least m and highest m numbers of arr[] .

Note that another optimal solution is to partition nums into the two subsequences [1] and [2,3]. Store the positive elements and their count in one map. But as we have to iterate through all subsets the time complexity for this approach is exponential O(n2^n). It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. All the elements of the array should be divided between the two subsets without leaving any element behind. Lowest 3 numbers are 1,2,3 and sum is 6. Note, this is the maximum difference possible. 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. This article is contributed by Shivam Pradhan (anuj_charm). By using our site, you Agree A subarray is a contiguous part of array, i.e., Subarray is an array that is inside another array. 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). Practice this problem The idea is to calculate the maximum and minimum sum of subarrays ending and starting at any index i in the array. https://www.geeksforgeeks.org/maximum-possible-difference-two-subsets-array/, n , 2 , .

(say count of integers is n, if n is even, each set must have n/2 elements and if n is odd, one set has (n-1)/2 elements and other has (n+1)/2 elements) is there DP approach for this problem. Maximum difference here is : 20 Explanation Here the highest 4 numbers are 22,16,14,13 and the sum is 65. Given an array S of N positive integers, divide the array into two subsets such that the sums of subsets is maximum and equal. Finally we print sum(A) sum(B). You have to make two subsets such that difference of their elements sum is maximum and both of them jointly contains all of elements of given array along with the most important condition, no subset should contain repetitive elements. Note: The subsets cannot any common element. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Affordable solution to train a team and make them project ready. All the elements of the array should be divided between the two subsets without leaving any element behind. So the main thing is to find two subsets of m numbers which have the highest sum and lowest sum. Lets now understand what we have to do using an example . Since two subsequences were created, we return 2. We have to find the sum of maximum difference possible from all subsets of given array. 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. The output of the program should be the maximum possible sum. Count items common to both the lists but with different prices, Count pairs from two linked lists whose sum is equal to a given value, Cumulative frequency of count of each element in an unsorted array, Find first non-repeating element in a given Array of integers. We are given an array arr [] of n non-negative integers (repeated elements allowed), find out the sum of maximum difference possible from contiguous subsets of the given array. We are given an array arr[] of n non-negative integers (repeated elements allowed), find out the sum of maximum difference possible from all subsets of the given array. The task here is to find the maximum distance between any two same elements of the array. So the highest or maximum difference is 12-6 which is 6. What is the difference between __str__ and __repr__? We can optimize the above solution using more efficient approaches discussed in below post.

A Computer Science portal for geeks. Same element should not appear in both the subsets. Finally return difference between two sums. 2. A subset can contain repeating elements. The minimum four elements are 1, 2, 3 and 4. Note: We may have a large answer, so we have to calculate the answer with mod 10^9 +7. Explanation: Maximum difference is between 6 and 1. You should make two subsets so that the difference between the sum of their respective elements is maximum. Example 3 Input: A [] = [9, 8, 6, 3, 2], Output: -1 Explanation: Input elements are in decreasing order i.e. Top 50 Array Coding Problems for Interviews, Introduction to Stack - Data Structure and Algorithm Tutorials, Maximum and minimum of an array using minimum number of comparisons, Check if a pair exists with given sum in given array, Kth Smallest/Largest Element in Unsorted Array, Python | Using 2D arrays/lists the right way, Array of Strings in C++ - 5 Different Ways to Create, Inversion count in Array using Merge Sort, Introduction and Array Implementation of Queue, Search an element in a sorted and rotated Array, Program to find largest element in an array, Sort an array of 0s, 1s and 2s | Dutch National Flag problem, Given Array of size n and a number k, find all elements that appear more than n/k times, Find Subarray with given sum | Set 1 (Non-negative Numbers), k largest(or smallest) elements in an array, Next Greater Element (NGE) for every element in given Array, Count ways to make the number formed by K concatenations of a numeric string divisible by 5, Count pairs in an array having sum of elements with their respective sum of digits equal, When all numbers are positive, put all numbers in subset A except the smallest positive number put that in subset B, and print, When all numbers are negative, put all numbers in subset B except the largest negative put that in subset A, and print. Suppose, we have an integer array. See your article appearing on the GeeksforGeeks main page and help other Geeks. We are going to use a Map. 15. Agree And for this we can conclude that all such elements whose frequency are 2, going to be part of both subsets and hence overall they dont have any impact on difference of subset sum.

Each element of the array should belong to exactly one of the subset. Another Approach ( Using STL) : The maximum absolute difference in the array will always be the absolute difference between the minimum and the maximum element from the array.Below is the implementation of the above approach: Time Complexity : O(n)Auxiliary Space: O(1), School Guide: Roadmap For School Students, Maximum possible difference between two Subarrays after removing N elements from Array, Maximum difference between two subsets of m elements, Maximum distance between two elements whose absolute difference is K, Maximum difference between two elements such that larger element appears after the smaller number, Minimum count of array elements that must be changed such that difference between maximum and minimum array element is N - 1, Maximum sum of a subsequence having difference between their indices equal to the difference between their values, Count number of elements between two given elements in array, Minimize the maximum difference between adjacent elements in an array, Maximum absolute difference between distinct elements in an Array, Smallest number that can replace all -1s in an array such that maximum absolute difference between any pair of adjacent elements is minimum.
