It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. 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. Note: We may have a large answer, so we have to calculate the answer with mod 10^9 +7. Hence, the sum of the minimum element of all subsets will be:min_sum = a1*2n-1 + a2*2n-2 + + an*20This sum can be computed easily in linear time with help of the Horner methodSimilarly, we can compute the sum of the maximum element of all subsets of arr[]. What will be the approach to solve this problem? Note: The subsets cannot any common element. Suppose max(s) represents the maximum value in any subset s whereas min(s) represents the minimum value in the set s. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Each element of the array should belong to exactly one of the subset. 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). What is the origin and basis of stare decisis? A Computer Science portal for geeks. For this we will be provided with an array containing one or two instances of few random integers. We can optimize the above solution using more efficient approaches discussed in below post. Suppose max (s) represents the maximum value in any subset 's' whereas min (s) represents the minimum value in the set 's'. Finally we print sum(A) sum(B). So the highest or maximum difference is 12-6 which is 6. 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. You need to sort first which you got it. 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. I have an array with N elements. The array may contain repetitive elements but the highest frequency of any element must not exceed two. For example, Consider the array [1, 2, 3, 4], There are 10 non-empty sub-arrays. 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. So the main thing is to find two subsets of m numbers which have the highest sum and lowest sum. You signed in with another tab or window. This program needs to output the location of these two elements (0 and 4) and their values (1 and 5). The number of such subsets will be 2. A subarray is a contiguous part of array, i.e., Subarray is an array that is inside another array. After storing frequencies of the negative elements, we are going to add up all the values of an array which are less than 0 and also that have a frequency of only 1. Why is sending so few tanks Ukraine considered significant? :book: [] GeeksForGeeks . You should make two subsets so that the difference between the sum of their respective elements is maximum. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. 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. Two elements should not be the same within a subset. Note: The subsets cannot any common element. Program for array left rotation by d positions. We are going to use a Map. What does "you better" mean in this context of conversation? 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. 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.
