Distinct

Given an array arrof size N. We have to pair the integers such that each integer should be in exactly one pair and each sum of pairs is consecutive and distinct. Formally, sum(arri +  arrj) + 1 = sum(arri1 + arrj1). Print the pairs of integers satisfying all the conditions. If it is not possible to find the pairs return -1.Examples:Input: N = 6, arr = {2, 3, 1, 4, 6, 5}Output:1 6 3 54 2Explanation: All pair’s sum is consecutive.Input: N = 8 arr = {8, 7, 1, 2, 3, 5, 6, 4}Output: -1Approach: This can be solved with the…

An earthquake in Alaska causing seismic waves to penetrate the Earth's innermost inner core. Credit: Drew Whitehouse, Son Phạm and Hrvoje Tkalčic. Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth's inner core, according to seismologists from The Australian National University (ANU). …

Given an array A of N integers, the task is to print the number of integers i from 1 to N, for which A contains exactly X distinct integers (for X = 0 to N-1) greater than AiExamples:Input: N = 6, A = {2, 7, 1, 8, 2, 8}Output: {2, 1, 2, 1, 0, 0}Explanation: Let us consider X = 2.A = 2: A contains 2 distinct integers greater than 2 (7 and 8)A = 7: A contains 1 distinct integer greater than 7 (8)A = 1: A contains 3 distinct integers greater than 1 (2, 7 and 8)A = 8: A doesn’t contain any distinct integers greater than 8A =…

Given an array A consisting of N positive integers, the task is to calculate the maximum XOR of the subarray of size K consisting of all distinct integers. If such subarray is not present then Print “-1”.Examples:Input: N = 10, A = , K = 4Output: 9Explanation : All Subarrays of size K with all distinct integers are , , and there XOR are 6, 5, 9 respectively. So Maximum XOR of subarray is 9. Input: N = 5, A = , K = 3Output: -1Explanation: Since there of no subarray of size K with all integers distinctNaive Solution: The…

Two Important SQL Clauses You Should KnowSource: Photo by geralt from PixabaySQL is a powerful tool when it comes to extracting data from a database — either from one or multiple tables.That said, there are some clauses that are particularly important when it comes to analysing data effectively.The two clauses covered in this article are the HAVING and DISTINCT clauses.Why do we need the HAVING clause?The purpose of the HAVING clause is to act as an equivalent to the WHERE clause when using a GROUP BY function.If you use…

Given an array arr with size N, the task is to find the minimum possible sum of distinct elements over all the prefixes of the array that can be obtained by rearranging the elements of the array.Examples:Input: arr = {3, 3, 2, 2, 3}, N = 5Output: 7Explanation: The permutation arr = {3, 3, 3, 2, 2} gives the minimum cost. It can be proved that this is the least cost that can be obtained.Input: arr = {7, 2, 2, 4, 7, 1}, N = 6Output: 13Explanation: The permutation arr = {7, 7, 2, 2, 1, 4} gives the minimum cost. It can be…
