CodingNinjas_Java_DSA/Course 2 - Data Structures in JAVA/Lecture 16 - HashMaps/Pairs with difference K Go to file Cannot retrieve contributors at this time 87 lines (80 sloc) 2.41 KB Raw Blame /* You are given with an array of integers and an integer K. You have to find and print the count of all such pairs which have difference K. The idea is that in the naive approach, we are checking every possible pair that can be formed but we dont have to do that. The idea is to insert each array element arr[i] into a set. We run two loops: the outer loop picks the first element of pair, the inner loop looks for the other element. The algorithm can be implemented as follows in C++, Java, and Python: Output: Also note that the math should be at most |diff| element away to right of the current position i. // Function to find a pair with the given difference in an array. By using our site, you Let us denote it with the symbol n. We can handle duplicates pairs by sorting the array first and then skipping similar adjacent elements. Think about what will happen if k is 0. It will be denoted by the symbol n. Are you sure you want to create this branch? output: [[1, 0], [0, -1], [-1, -2], [2, 1]], input: arr = [1, 7, 5, 3, 32, 17, 12], k = 17. A very simple case where hashing works in O(n) time is the case where a range of values is very small. You are given with an array of integers and an integer K. You have to find and print the count of all such pairs which have difference K. Note: Take absolute difference between the elements of the array. Cannot retrieve contributors at this time 72 lines (70 sloc) 2.54 KB Raw Blame Given an integer array and a positive integer k, count all distinct pairs with differences equal to k. Method 1 (Simple):A simple solution is to consider all pairs one by one and check difference between every pair. 1. //System.out.println("Current element: "+i); //System.out.println("Need to find: "+(i-k)+", "+(i+k)); countPairs=countPairs+(map.get(i)*map.get(k+i)); //System.out.println("Current count of pairs: "+countPairs); countPairs=countPairs+(map.get(i)*map.get(i-k)). The following line contains an integer, that denotes the value of K. The first and only line of output contains count of all such pairs which have an absolute difference of K. public static int getPairsWithDifferenceK(int arr[], int k) {.

Learn more about bidirectional Unicode characters. This solution doesnt work if there are duplicates in array as the requirement is to count only distinct pairs. Read More, Modern Calculator with HTML5, CSS & JavaScript. * Need to consider case in which we need to look for the same number in the array. if value diff < k, move r to next element. Input Format: The first line of input contains an integer, that denotes the value of the size of the array. O(nlgk) time O(1) space solution * http://www.practice.geeksforgeeks.org/problem-page.php?pid=413. 2) In a list of . // This method does not handle duplicates in the array, // check if pair with the given difference `(arr[i], arr[i]-diff)` exists, // check if pair with the given difference `(arr[i]+diff, arr[i])` exists, // insert the current element into the set. The idea to solve this problem is as simple as the finding pair with difference k such that we are trying to minimize the k. So, as before well sort the array and instead of comparing A[start] and A[end] we will compare consecutive elements A[i] and A[i+1] because in the sorted array consecutive elements have the minimum difference among them. HashMap map = new HashMap<>(); if(map.containsKey(key)) {. Keep a hash table(HashSet would suffice) to keep the elements already seen while passing through array once. Therefore, overall time complexity is O(nLogn). Take two pointers, l, and r, both pointing to 1st element. Read our. Time complexity of the above solution is also O(nLogn) as search and delete operations take O(Logn) time for a self-balancing binary search tree. Then (arr[i] + k) will be equal to (arr[i] k) and we will print our pairs twice! This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Inside the package we create two class files named Main.java and Solution.java. * Given an integer array and a non-negative integer k, count all distinct pairs with difference equal to k, i.e., A[ i ] - A[ j ] = k. * * @param input integer array * @param k * @return number of pairs * * Approach: * Hash the input array into a Map so that we can query for a number in O(1) The time complexity of the above solution is O(n) and requires O(n) extra space. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. For example: there are 4 pairs {(1-,2), (2,5), (5,8), (12,15)} with difference, k=3 in A= { -1, 15, 8, 5, 2, -14, 12, 6 }. Given an unsorted integer array, print all pairs with a given difference k in it. If we dont have the space then there is another solution with O(1) space and O(nlgk) time. Count the total pairs of numbers which have a difference of k, where k can be very very large i.e. pairs_with_specific_difference.py. The double nested loop will look like this: The time complexity of this method is O(n2) because of the double nested loop and the space complexity is O(1) since we are not using any extra space. The overall complexity is O(nlgn)+O(nlgk). This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. * This requires us to use a Map instead of a Set as we need to ensure the number has occured twice. This is a negligible increase in cost. Time Complexity: O(n2)Auxiliary Space: O(1), since no extra space has been taken. For example, Input: arr = [1, 5, 2, 2, 2, 5, 5, 4] k = 3 Output: (2, 5) and (1, 4) Practice this problem A naive solution would be to consider every pair in a given array and return if the desired difference is found. Following are the detailed steps. (5, 2) We can improve the time complexity to O(n) at the cost of some extra space. # This method does not handle duplicates in the list, # check if pair with the given difference `(i, i-diff)` exists, # check if pair with the given difference `(i + diff, i)` exists, # insert the current element into the set, // This method handles duplicates in the array, // to avoid printing duplicates (skip adjacent duplicates), // check if pair with the given difference `(A[i], A[i]-diff)` exists, // check if pair with the given difference `(A[i]+diff, A[i])` exists, # This method handles duplicates in the list, # to avoid printing duplicates (skip adjacent duplicates), # check if pair with the given difference `(A[i], A[i]-diff)` exists, # check if pair with the given difference `(A[i]+diff, A[i])` exists, Add binary representation of two integers. # Function to find a pair with the given difference in the list.
