By using our site, you Note sort(arr[],int) is assumed to return the sorted array. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. In the find_diff() function we are passing the input array and its length and returning the maximum difference of the sum of sets of m elements. Split Array into K non-overlapping subset such that maximum among all subset sum is minimum, Sum of maximum and minimum of Kth subset ordered by increasing subset sum, Maximum size of subset such that product of all subset elements is a factor of N, Maximum Subset Sum possible by negating the entire sum after selecting the first Array element, Largest value of K that a set of all possible subset-sum values of given Array contains numbers [0, K], Smallest subset of maximum sum possible by splitting array into two subsets, Maximum subset sum having difference between its maximum and minimum in range [L, R], Find maximum subset-sum divisible by D by taking at most K elements from given array, Find subset with maximum sum under given condition, Find sum of difference of maximum and minimum over all possible subsets of size K. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Here also, we need to ignore those elements that come several times or more than once. Suppose max (s) represents the maximum value in any subset 's' whereas min (s) represents the minimum value in the set 's'. Two elements should not be the same within a subset. 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. Return the minimum possible absolute difference. We need to find the sum of max(s)-min(s) for all possible subsets. When was the term directory replaced by folder? Hashing provides an efficient way to solve this question. Output: The maximum absolute difference is 19. Algorithm with time complexity O(n log n): Time Complexity: O(n log n)Auxiliary Space: O(1), Time Complexity: O(n)Auxiliary Space: O(n), Some other interesting problems on Hashing, Divide array in two Subsets such that sum of square of sum of both subsets is maximum, Maximum possible difference of sum of two subsets of an array | Set 2, Maximum number of subsets an array can be split into such that product of their minimums with size of subsets is at least K, Partition an array of non-negative integers into two subsets such that average of both the subsets is equal, Split array into maximum possible subsets having product of their length with the maximum element at least K, Smallest subset of maximum sum possible by splitting array into two subsets, Sum of subsets of all the subsets of an array | O(3^N), Sum of subsets of all the subsets of an array | O(2^N), Sum of subsets of all the subsets of an array | O(N), Split array into minimum number of subsets such that elements of all pairs are present in different subsets at least once. Approach: The given problem can be solved with the help of the Greedy Approach using the Sliding Window Technique. Input: arr[] = {1, -5, 3, 2, -7}Output: 18Explanation: The partitions {1, 3, 2} and {-5, -7} maximizes the difference between the subsets. The minimum four elements are 1, 2, 3 and 4. I suppose you should check two cases: the difference between the M lowest elements and the N-M highest ones, as you already did; and instead the difference between the M highest and the N-M lowest.

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. Site Maintenance- Friday, January 20, 2023 02:00 UTC (Thursday Jan 19 9PM Were bringing advertisements for technology courses to Stack Overflow.

Then we are going to store it in the map with its number of occurrences. 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 the difference of subset-sum. i.e 1,2,3,4,6 is given array we can have max two equal sum as 6+2 = 4+3+1. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. (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.

Approach: The maximum absolute difference in the array will always be the absolute difference between the minimum and the maximum element from the array. But as we have to iterate through all subsets the time complexity for this approach is exponential O(n2^n). 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. 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. acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Full Stack Development with React & Node JS (Live), Data Structure & Algorithm-Self Paced(C++/JAVA), Full Stack Development with React & Node JS(Live), GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Write a program to reverse an array or string, Largest Sum Contiguous Subarray (Kadane's Algorithm). By using our site, you For example, for the array : {1,2,3}, some of the possible divisions are a) {1,2} and {3} b) {1,3} and {2}. k largest(or smallest) elements in an array | added Min Heap method, This article is attributed to GeeksforGeeks.org. We are going to use a Map. This work is licensed under Creative Common Attribution-ShareAlike 4.0 International A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. The only difference is that we need to iterate the elements of arr[] in non-increasing order. 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. Maximum Sum of Products of Two Array in C++ Program, Find the maximum possible value of the minimum value of modified array in C++, Maximum product subset of an array in C++. Suppose max (s) represents the maximum value in any subset 's' whereas min (s) represents the minimum value in the set 's'. Here we will first sort the elements of array arr[]. Lets now understand what we have to do using an example . Approach: The maximum absolute difference in the array will always be the absolute difference between the minimum and the maximum element from the array. We are going to use two Maps. Same element should not appear in both the subsets. 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. Then we will find the last occurrence of that same number and store the difference between indexes. acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Full Stack Development with React & Node JS (Live), Data Structure & Algorithm-Self Paced(C++/JAVA), Full Stack Development with React & Node JS(Live), GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Separate Chaining Collision Handling Technique in Hashing, Open Addressing Collision Handling technique in Hashing, Index Mapping (or Trivial Hashing) with negatives allowed, Union and Intersection of two Linked List using Hashing, Minimum operation to make all elements equal in array, Maximum distance between two occurrences of same element in array, First element occurring k times in an array.
