给定一个未经排序的整数数组,找到最长且连续的的递增序列。 示例1: 输入:[1,3,5,4,7]输出:3解释: 最长连续递增序列是[1,3,5], 长度为3。 尽管[1,3,5,7]也是升序的子序列, 但它不是连续的,因为5和7在原数组里被4隔开。 示例2: 输入: [2,2,2,2,2]输出: 1解释: 最长连续递增序列是 [2],...

Leetcode 300. Longest Increasing Subsequence 编程算法 **解析:**Version 1,最长递增子序列,典型的动态规划问题,定义状态:以nums[i]作为结尾元素的最长递增子序列的长度,状态转移方程:遍历nums[i]之前的元素nums[j],如果nums[i] > nums[j],则其最长递增子序列的长度为max(dp[i], dp[j] + 1),遍历之后...
Given an unsorted array of integers, find the length of longest increasing subsequence. Example: Input: [10,9,2,5,3,7,101,18]Output: 4Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4.Note: There may be more than one LIS combination, it is on...
【Leetcode】300. Longest Increasing Subsequence 1.最长递增子序列: 思路是dp,先说一个很general的idea。子问题为dp[i],以array[i]为结尾的最长子序列的最后一个元素。那么只要遍历之前的所有dp即可,取可行的里面的最大值。复杂度On2. public int maxISLength(int[] array){...
题目链接:https://leetcode.com/problems/longest-increasing-subsequence/ 题目: Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given[10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is[2, 3, 7, 101], therefore the leng...
题目描述: LeetCode 674. Longest Continuous Increasing Subsequence Given an unsorted array of integers, find the length of longest continuous increasing subsequence. Example 1: Input: [1,3,5,4,7] Output: 3 Explanation: The longest continuous increasing s
这道题让我们求最长递增子串Longest Increasing Subsequence的长度,简称LIS的长度。我最早接触到这道题是在LintCode上,可参见我之前的博客Longest Increasing Subsequence 最长递增子序列,那道题写的解法略微复杂,下面我们来看其他的一些解法。首先来看一种动态规划Dynamic Programming的解法,这种解法的时间复杂度为O(n2),...
