maximum possible difference of two subsets of an array. So, overall complexity is O(N^3*LgN), but most likely you can avoid sorting on every iteration, instead sort whole array only once and update parts in O(1) on every iteration. What is the maximum possible value of an integer in C# ? By using our site, you The number of such subsets will be 2, Subsets not containing elements a1, a2,, ai-1 but containing ai: These subsets can be obtained by taking any subset of {ai+1,ai+2,, an}, and then adding ai into it. You have to return the subset of that set so that the mean - median is maximum for that subset. Asking for help, clarification, or responding to other answers.

Maximum difference between two elements is equal to solve Maximum Subarray? Does the policy change for AI-generated content affect users who (want to) Python, finding the max difference in an arraylist, Maximize the sum between two lists of integers? For example, consider S = {10, 20, 15, 5, 25}. C++ Program to Generate All Pairs of Subsets Whose Union Make the Set. Which group of elements was missing from Mendeleevs original periodic table? Find the sum of all subarray minimums, and subtract this from the first sum. Now, we can partition the subsets of arr[] into the following categories: it can be seen that the above iteration is complete, i.e., it considers each subset exactly once. You can suggest the changes for now and it will be under the articles discussion tab. Input: arr[] = {2, 6, 8, 10, 20, 25}, K = 26Output: 3Explanation:Subset having maximum pair sum less than or equal to K(=26) are: {{2, 6, 8, 10}, {20}, {25}}.Therefore, the required output is 3. Dividing the items into subset in a way such that the difference in the summation of elements between the two subset is the maximum. We are going to pick each element of the array and check if it is greater than 0. rather than "Gaudeamus igitur, *dum iuvenes* sumus!"? What is the maximum possible value of an integer in C# ?

The sum of the maximum/ minimum element of each subset can be computed easily by iterating through the elements of each subset. There are about N possible medians, sorting takes O(N*lgN), on every iteration you need to compute up to N means, you can do it in O(N). Initializing to None might be ever so slightly faster. You will be notified via email once the article is available for improvement.

Sample implementation of the whole algorithm (in Python): Alternatively, as noticed by @kcsquared, you can use 2 stream, one for max sum and the other for min sum, and subtract them. Suppose max(s) represents the maximum value in any subset s whereas min(s) represents the minimum value in the set s. @AndyTurner, here contiguous means elements which are next to each other. Sort both parts L and R, then start choosing in pair lr maximal elements from both parts and with addition of every next element recompute mean, store arrangement with the best difference.
