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…
输入为一个数组A和一个整数k,找到数组中 所有的数值对pairs(i,j),其中A[i]和A[j]之间差的绝对值是k。比如【3,1,4,1,5】,k=2,ouput=2,这样的差值对是(1,3)和(3,5),其中1虽然在数组中出现过2次,但是只算一次。(题目:https://leetcode.com/problems/k-diff-pairs-in-an-array/#/description...
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. Example 1: Input: [3, 1, 4...

解法1:对k=0,k>0,k<0的处理不同;k=0的时候,统计出nums中每一个元素在nums出现的个数是否大于1,如果大于1则count+1;k>0的时候,用set(nums)中的元素加上k,判断是否在nums中,如果存在,则count+1;k<0时,直接返回0; classSolution(object):deffindPairs(self,nums,k):""" ...
The kmeans function returns NaN for the corresponding value in the output argument idx. Data Types: single | double k— Number of clusters positive integer Number of clusters in the data, specified as a positive integer. Data Types: single | double Name-Value Arguments Specify optional pairs ...

Let n and k be positive integers with k ≤ n. From an n × n array of dots, a k × k array of dots is selected. The figure above shows two examples where the selected k × k array is enclosed in a square. How many pairs (n, k) are
