532.K-diff Pairs in an Array 解题思路。 1、读题,数组中二数之差的绝对值为k。 2、只要遍历数组,每一个元素加上K值,还在原来的数组中,就找到一个解。 3、如果用数组遍历,会超时,通不过LeetCode 的测试,变…
Given an array of integersnumsand an integerk, returnthe number of unique k-diff pairs in the array. A k-diff pair is an integer pair(nums[i], nums[j]), where the following are true: 0 <= i, j < nums.length i != j nums[i] - nums[j] == k Notice that|val|denotes the ...
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. ...
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. A k-diff pair is an integer pair (nums[i], nums[j]), where the following are
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. ...
You are given an arraynumsthat consists of non-negative integers. Let us definerev(x)as the reverse of the non-negative integerx. For example,rev(123) = 321, andrev(120) = 21. A pair of indices(i, j)isniceif it satisfies all of the following conditions: ...
Given two integers n and k, find how many different arrays consist of numbers from 1 to n such that there are exactly k inverse pairs. We define an inverse pair as following: For ith and jth element in the array, if i < j and a[i] > a[j] then it’s an inverse pair; Otherwis...
