Minimum distance of adjacent pair in array. The minimum absolute difference must be a difference between two consecutive elements in the sorted array. g. Time Complexity: O (n^2), where n is the total number of elements in the array. length, is valid if both i <= j and nums1[i] <= nums2[j]. If no such value exists, return -1. Jul 23, 2025 · The outer loop for selecting the first element (x) and the inner loop is for traversing the array in search for the other element (y) and taking the minimum distance between them. You are given an array, arr []. Sort the array, and go through the pairs of adjacent numbers looking for the smallest difference: Nov 20, 2020 · Emit a candidate pair (min (minimum distance, array number − maximum number), array number). May 22, 2017 · Namely, one could walk through the input array and store the first occurrence of an element within a map, and for every subsequent occurrence find the distance between that occurrence and the first index of that element in the map. Minimum Distance between two 3's = 5 Minimum Distance between two 5's = 3 Therefore, Minimum distance between any two equal elements in the Array = 3 Naive Approach: The simplest approach is using two nested for loops to form each and every combination. Now, find the distance between the indices of adjacent elements of the sorted array using the Map. The distance of the pair is j - i . Below is the implementation of the above approach: Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. This approach has a time complexity of O (N^2), where N is the size of the input array. Can you solve this real interview question? Maximum Distance Between a Pair of Values - You are given two non-increasing 0-indexed integer arrays nums1 and nums2 . For each pair, compute the absolute difference. Input : arr[] = {1, 2, 1} Output : 2 Brute Force Approach: The simplest approach is to find all pair of indexes of minimum element and calculate minimum distance. Finally, print all the adjacent pairs having differences equal to the minimum absolute difference. We can first sort the array in ascending order and then find the minimum difference by comparing adjacent elements. Initialize an array of integers arr [] and find its size n. A k-diff pair is an integer pair (nums[i], nums[j]), where the following are true: Jul 23, 2025 · The brute force approach calculates the difference between the left and right subarrays minimum of each element in the input array by iterating through the array arr [] and getting the minimum of the elements to the left and right of each element separately. Sep 2, 2012 · The minimum difference will be one of the differences from among the consecutive pairs in sorted order. Cull the candidate pairs to leave only the efficient frontier. Initialize a variable mini to a large value (e. , INT_MAX) to keep track of the minimum distance. Example a = [3, 2, 1, 2, 3] There are two matching pairs of values: 3 and 2. If there Jul 23, 2025 · Compare all adjacent pairs in the sorted array and find the minimum absolute difference between all adjacent pairs. If the difference equals the current minimum, append this pair to the list. If the min was less than or equal to minimum distance, increment the frontier iterator. Rabin formulated a randomized algorithm for finding the closest pair in and proved it achieved a linear time complexity with high probability. Apr 19, 2023 · So the minimum distance is 7-5 = 2. If the min was less than or equal to array number − maximum number, increment the array iterator. If that distance is less than the current minimum, then we update that minimum. Jun 23, 2025 · Now, find the distance between the indices of adjacent elements of the sorted array using the Map. Examples: Input: arr [] = [1, 2, 3, 2], x = 1, y = 2 Output: 1 Explanati Jul 12, 2025 · Output: 3 Explanation: There are two matching pairs of values: 3 and 5 in this array. Find the minimum index based distance between two distinct elements of the array, x and y. Mar 18, 2024 · In 1976, Michael O. Maintain the minimum distance for each pair of adjacent elements in the step above. A pair of indices (i, j), where 0 <= i < nums1. Return -1, if either x or y does not exist in the array. Apr 18, 2023 · In this post, we will solve HackerRank Minimum Distances Problem Solution. Alternatively, we can insert all the elements into a map and then iterate through the map, comparing adjacent elements. Sep 25, 2024 · Initialize two indices i1 and i2 to -1 to store the most recent indices of x and y found during the traversal of the array. This will work because they are in ascending order, so the number with the nearest value is adjacent. Sort the array, then go over it once more and check the distance between the sorted items. Given a find the minimum distance between any pair of equal elements in the array. Return the maximum distance of any valid pair (i, j). After the completing the above steps, print the minimum distance formed. Iterate through the sorted array, comparing each pair of adjacent elements. Jul 23, 2025 · Find the minimum difference between any two elements using Map: We can solve this problem using a map. If this difference is less than the current minimum, update the minimum and reset the list of pairs. The distance between two array values is the number of indices between them. length and 0 <= j < nums2. Mar 10, 2023 · Sort the given array arr []. . hmr ofv icu zlj wuh vii jve hhr kja vaq hiy ogr rss jqb bbm
