In this array, find count of distinct pairs that sum to target value. For example, given a = [1, 1, 2, 3] and k = 4. There is only one distinct pair (1, 3) fulfilling the requirement. The result should be 1. Sprint Training Aug 31, 2015 · The solution is pretty straight-forward, just read the code :).

HackerRank 258,995 views. 9:06 ... Preparing for a Python Interview: ... Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array. Here a k-diff pair is defined as an integer pair (i, j), where i and j are both numbers in the array and their absolute difference is k. Sep 17, 2011 · Programming Interview Questions 1: Array Pair Sum Posted on September 17, 2011 by Arden Once again it’s the college recruiting season of the year and tech companies started the interview process for full time and internship positions. Jun 15, 2017 · So now the frequency array holds the information of the number of distinct values in the given array. Next we traverse the whole frequency array and if it is not 0 (the index is present as an element in the given array) we divide the value by 2 to determine the number of pairs of that value and add it to our answer. Hackerrank describes this problem as easy. Note: Hackerrank has strict execution time limits (typically 2 seconds for C++ code) and often a much wider input range than the original problem. In my opinion, Hackerrank's modified problems are usually a lot harder to solve. As a rule thumb: brute-force is rarely an option. Links HackerRank Solutions in Python3.

Given an integer array and a positive integer k, count all distinct pairs with difference equal to k. Examples: Input: arr[] = {1, 5, 3,… Read More » 1st line contains N & K (integers). 2nd line contains N numbers of the set. All the N numbers are assured to be distinct. Now the question is from hackerrank. I got a solution for the question but it doesn't satisfy the time-limit for all the sample test cases. I'm not sure if its possible to use another algorithm but I'm out of ideas. This is the "Pairs with Positive Negative values" problem from geeksforgeeks.org.Given an array of distinct integers, print all the pairs having positive value and negative value of a number that exists in the array. Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array.

Python's "in" operator has different time complexities depending on the data structure being used. If it's a list it might reach O(N) very easily, but using a Dictionary - Python's Hashtable - or a Set, both use the __hash__ method, is O(1). It might reach O(N) if the __hash__ is not well implemented just like samirsahu said. We define a magic square to be an matrix of distinct positive integers from 1 to n 2 where the sum of any row, column, or diagonal (of length n) is always equal to the same number (i.e., the magic constant). Consider a matrix, s, of integers in the inclusive range [1, 9]. If you have already attempted the problem (solved it), you can access others code.

The problem of the modulo operator can be treated in different ways. Since we are using Python as implementation language we can completely ignore it, as it can handle arbitrarily large integers. However, we can also solve it as we have done for Project Euler problem 48. In general we have the formula This section covers various examples in Python programming Language. These Programs examples cover a wide range of programming areas in Computer Science. Every example program includes the problem description, problem solution, source code, program explanation and run time test cases.
