Solution: HackerRank’s Automated Assessments Increased Quality and Diversity Want to learn more? So, if we have a given sample test case like: We can then iterate over all these pairs and the find the difference. Along with the array, you are also given a target value k. If you pick up any 2 integers from the array, they would form a pair and have some difference x - y. Since the array is sorted, use binary search to find the element in the sorted array. Pairs hacker rank solution in java is given in this video. Here I make my solutions publicly available for other enthusiasts to learn from and to critique. ***Solution to Day 21 skipped, because Python implementation was not available at the time of completion.
