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 p pairs of indices of nums such that the maximum difference amongst all the pairs is minimized. Als
Return the maximum such product difference. Example 1: Input: nums = [5,6,2,7,4] Output: 34 Explanation: We can choose indices 1 and 3 for the first pair (6, 7) and indices 2 and 4 for the second pair (2, 4). The product difference is (6 * 7) - (2 * 4) = 34. 1...

532. K-diff Pairs in an Array Given an array of integers and an integerk, you need to find the number ofuniquek-diff pairs in the array. Here ak-diffpair is defined as an integer pair (i, j), whereiandjare both numbers in the array and theirabsolute differenceisk....
Slightly different way to move pointers, also two pointers, move right pointer as main loop, move right pointer to the last element has the same value, if difference is bigger than k, move left, otherwise ++count. The following code is refactored during sleeping mode... ...
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 theirabsolute differenceis k. ...
This problem is similar but not the same with Number of Airplanes in the sky. Similarity: both problems are given activities with a start and end time. Difference: This problem looks for the max result "horizontally", Number of Airplanes in the sky looks for the max result "vertically". ...
