Suppose max(s) represents the maximum value in any subset s whereas min(s) represents the minimum value in the set s. Input . Subsets need not be contiguous always. 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. Suppose, we have an integer array. A subarray is a contiguous part of array, i.e., Subarray is an array that is inside another array. 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. The summation of subset 1 = 2 + 3 + 4 = 9, The summation of subset 2 = 6+ 5 + 10 = 21. Note that the above solution is in Pseudo Polynomial Time (time complexity is dependent on numeric value of input). Suppose we have an array and a number m, then we will first find the sum of highest m numbers and then subtract the sum of lowest m numbers from it to get the maximum difference. Subsets containing element a1: These subsets can be obtained by taking any subset of {a2,a3,, an} and then adding a1 into it.
