The difference in subset = 21 - 9 = 12. Maximum difference between two subsets of m elements Given an array of n integers and a number m, find the maximum possible difference between two sets of m elements chosen from given array. A Computer Science portal for geeks. Making statements based on opinion; back them up with references or personal experience. 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. While building up the subsets, take care that no subset should contain repetitive elements. The sum of the maximum/ minimum element of each subset can be computed easily by iterating through the elements of each subset. Not working when my input array is {100, 100, 150} and M = 2; Its giving me answer 50. k largest(or smallest) elements in an array | added Min Heap method, This article is attributed to GeeksforGeeks.org. Approach used in the below program as follows Take input array arr [] and a number m for making sets 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. Lowest 4 numbers are 8,10,13,14 and the sum is 45 . Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, maximum difference in the summation of two subset, Flake it till you make it: how to detect and deal with flaky tests (Ep. So, if the input is like A = [1, 3, 4], then the output will be 9. Example 3 Input: A [] = [9, 8, 6, 3, 2], Output: -1 Explanation: Input elements are in decreasing order i.e. Agree Examples: Input: arr [] = {1, 3, 2, 4, 5} Output: 13 So the highest or maximum difference is 65-45 which is 20. Then we are going to store it in the map with its number of occurrences. How to automatically classify a sentence or text based on its context? Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. 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. By using our site, you This program needs to output the location of these two elements (0 and 4) and their values (1 and 5). We can optimize the above solution using more efficient approaches discussed in below post. Consider both cases and take max. Double-sided tape maybe? 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. Input : arr [] = 1 2 3 4 5 m = 4 Output : 4 The maximum four elements are 2, 3, 4 and 5. An array can contain repeating elements, but the highest frequency of an element should not be greater than 2. The difference between the maximum and minimum value in the second subsequence is 3 - 3 = 0. 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. Below is the implementation of the above approach: C++ Java Python3 C# PHP Javascript #include <bits/stdc++.h> using namespace std; int maxAbsDiff (int arr [], int n) { int minEle = arr [0]; How to split a string in C/C++, Python and Java?

A Computer Science portal for geeks. and is attributed to GeeksforGeeks.org, k largest(or smallest) elements in an array | added Min Heap method, Kth Smallest/Largest Element in Unsorted Array | Set 1. 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[] . A Computer Science portal for geeks. lualatex convert --- to custom command automatically? Output: The maximum sum is 26 The maximum sum is formed by subsequence { 1, 9, 5, 11 } Practice this problem The problem is similar to the 0/1 Knapsack problem, where for every item, we have two choices - to include that element in the solution or exclude that element from the solution. We will pick each element from the array starting from the left. Return the minimum possible absolute difference. Now you can take M elements from either from start or from the end. 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. 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.
