Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i and j is at most k. 解题思路: 暴力枚举会LTE,解题思路是用sortedSet来解决,sort…

Given an array of integers, find out whether there are two distinct indices i and j in the array such that the absolute difference between nums[i] and nums[j] is at most t and the absolute difference between i and j is at most k. Example 1: Input: nu…

Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i and j is at most k. 思想借鉴:维持一个长度为k的window, 每次检查新的值是否与原来窗口中的…

Find all possible combinations of k numbers that add up to a number n, given that only numbers from 1 to 9 can be used and each combination should be a unique set of numbers. Ensure that numbers within the set are sorted in ascending order. Example 1…

220. 存在重复元素 III 给定一个整数数组,判断数组中是否有两个不同的索引 i 和 j,使得 nums [i] 和 nums [j] 的差的绝对值最大为 t,并且 i 和 j 之间的差的绝对值最大为 ķ. 示例 1: 输入: nums = [1,2,3,1], k = 3, t = 0 输出: true 示例 2: 输入: nums = [1,0,1,1], k = 1, t = 2 输出: true 示例 3: 输入: nums = [1,5,9,1,5,9], k = 2, t = 3…

题目: Given an array of integers, find out whether there are two distinct indices i and j in the array such that the difference between nums[i] and nums[j] is at most t and the difference between i and j is at most k. 提示: 看到题目之后,马上想到了题目应该是要利用一个长度为k的划窗,…
