Pair with difference k leetcode. The value of |x| is defined as: * x if x >= 0.

Pair with difference k leetcode 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. K diff Pairs in an Array | Leetcode 532 | Arrays Ayushi Sharma 48. Can you solve this real interview question? Count Number of Pairs With Absolute Difference K - Given an integer array nums and an integer k, return the number of pairs (i, j) where i < j such that |nums [i] - nums [j]| == k. Better than official and forum solutions. Can you solve this real interview question? K-diff Pairs in an Array - Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. 6K subscribers 395 LeetCode 532: K-diff Pairs in an Array in Python is a delightful pair-finding challenge. Can you solve this real interview question? Minimize the Maximum Difference of Pairs - You are given a 0-indexed integer array nums and an integer p. Find K-th Smallest Pair Distance LeetCode Was Hard Until I Learned THESE 8 Patterns (With Templates!) In-depth solution and explanation for LeetCode 532. * -x if x < 0. A k-diff pair is an integer pair (nums[i], nums[j]), where the following are true: The K-diff Pairs in an Array problem asks you to find the number of unique pairs in an array nums where the absolute difference between the two elements of each pair is exactly k. Can you solve this real interview question? Minimum Absolute Difference - Given an array of distinct integers arr, find all pairs of elements with the minimum absolute difference of any two elements. Multiply the frequencies of number and number+k to get the count of valid pairs for that particular value. Can you solve this real interview question? K-diff Pairs in an Array - Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. In-depth solution and explanation for LeetCode 2006. Key Insights Use a frequency table (hash table) to count the occurrences of each number. For each pair, if the absolute difference is equal to k, increment the count by 1. Hash map with single pass is your fast track, while sorting with two pointers offers a sorted twist. Find p pairs of indices of nums such that the maximum difference amongst all the pairs is minimized. Since k is always >= 1, we can safely use the frequency method without worrying about handling the k == 0 case. K-diff Pairs in an Array in Python, Java, C++ and more. Smallest Absolute Difference gfg problem of the day | Leetcode 719. Given an array of integers and an integer k, you need to find the number of unique k-diff pairs in the array. Intuitions, example walk through, and complexity analysis. Description Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. Input: nums = [1,3], k = 3 Output: 0 Explanation: There are no pairs with an absolute difference of 3. Given an array of integers nums and an integer k, return the number of unique k-diff pairs in the array. Also, ensure no index appears more than once amongst the p pairs. Count Number of Pairs With Absolute Difference K in Python, Java, C++ and more. Jul 23, 2025 · [Naive Approach] Generating all pairs - O (n^2) Time and O (1) Space The basic idea is to use two nested loops to generate all pairs in arr []. For each unique number, check if the number + k exists in the frequency table. The value of |x| is defined as: * x if x >= 0. Note that for a pair of elements at the index i and j, the difference of this . wkc wrnhje ssejhyk qtupq krtlmj wsf vhuqbnrt hbhe gosvbgb aijisc qwfqho ushqbk hklrd jpkold sdssw
