Given an array S of N positive integers, divide the array into two subsets such that the sums of subsets is maximum and equal. Example 3: All the elements of the array should be divided between the two subsets without leaving any element behind. As we have to compute the sum of the maximum element of each subset, and the sum of the minimum element of each subset separately here is an efficient way to perform this calculation. What does "you better" mean in this context of conversation? Explanation: Possible partitions are: {2, 4, 6} Approach: The idea is to observe that if there is no such pair i, j such that |arr [i] - arr [j]| = 1, then it is possible to put all the elements in the same partition, otherwise divide them into two partitions.
