To partition nums, put each element of nums into one of the two arrays. 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. no larger element appears after the smaller element. The algorithm for this method is: For each recursion of the method, divide the problem into two sub problems such that: So the required minimum number of partitions is always 1 or 2. So we have to put at least one element in both of them. 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. 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.

The only difference is that we need to iterate the elements of arr[] in non-increasing order. All the elements of the array should be divided between the two subsets without leaving any element behind. An array can contain repeating elements, but the highest frequency of an element should not be greater than 2. 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. Find the sum of maximum difference possible from all subset of a given array. (If It Is At All Possible), Two parallel diagonal lines on a Schengen passport stamp. (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. For this we will be provided with an array containing one or two instances of few random integers. In list [1,2,3,4,5] the maximum difference is 4 (between elements 1 and 5) using for loops. Connect and share knowledge within a single location that is structured and easy to search. The array may contain repetitive elements but the highest frequency of any element must not exceed two.
