A set of s DNA strands where the definition of each strand has three components,start ,end , and d, where string is a DNA for which genes gstart,…,gend are healthy. For example, the array [1,1,1,2] has two different valid pairs: (1,1) and (1,2). c) Finally, the problem is marked as "Easy" by the HackerRank folks One wrong approach to follow is to attempt to actually delete characters: you'll end up with massive permutations and it will become intractable. We can do this by creating k buckets where bucket i counts each number n where n % k = i. So it will ask to out put either the total unique pairs of elements from the array having the difference or just total count of that pairs. Java There is an Enumerable.
