Follow up: Could you improve it to O(nlogn) time complexity? 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。博主最早接触到这道题是在 LintCode 上,可参见博主之前的博客Longest Increasing Subsequence,那道题写
Given an integer array nums, return the length of the longest strictly increasing subsequence. Example 1: Input: nums = [10,9,2,5,3,7,101,18] Output: 4 Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4. Example 2: Input: nums = [0,1,0,...
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...
【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){ int[] dp = new int[array.l...
https://leetcode.cn/problems/longest-increasing-subsequence 给你一个整数数组 nums ,找到其中最长严格递增子序列的长度。 子序列 是由数组派生而来的序列,删除(或不删除)数组中的元素而不改变其余元素的顺序。例如,[3,6,2,7] 是数组 [0,3,1,6,2,2,7] 的子序列。
