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. 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 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…

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. 题目大意:给定一个整数数组nums,找出…

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,…

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. 链接: http://leetcode.com/problems/c…

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 nums [i] 和 nums [j] 的绝对差值最大为 t,并且 i 和 j 之间的绝对差值最大为 k. 详见:https://leetcode.com/problems/contains-duplicate-iii/description/ Java实现: TreeSet数据结构(Java)使用红黑树实现,是平衡二叉树的一种.该数据结构支持如下操作:floor()方法返set中≤给定元素的最大元素:如果不存在这样的元素,则返回…

因为要考虑超时问题,所以虽然简单的for循环也可以做,但是要用map等内部红黑树实现的容器. 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 bet…
