What is the difference between Python's list methods append and extend? The difference between the maximum and minimum value in the first subsequence is 2 - 1 = 1. In general, for an array of size n, there are n* (n+1)/2 non-empty subarrays. You have to make two subsets such that difference of their elements sum is maximum and both of them jointly contains all of elements of given array along with the most important condition, no subset should contain repetitive elements. Note that another optimal solution is to partition nums into the two subsequences [1] and [2,3]. The same thing will be done with negative elements we will pick every element of an array and this time we will check if it is less than 0. The task here is to find the maximum distance between any two same elements of the array. 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. We make use of First and third party cookies to improve our user experience. Affordable solution to train a team and make them project ready. We need to find the sum of max(s)-min(s) for all possible subsets. We can optimize the above solution using more efficient approaches discussed in below post.
