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。 示例1: 输入:nums = [10,9,2,5...
(Java) LeetCode 300. Longest Increasing Subsequence —— 最长上升子序列 Given an unsorted array of integers, find the length of longest increasing subsequence. Example: Input: [10,9,2,5,3,7,101,18] Output: 4 Explanation: The longest increasing subsequence is [2,3,7,101], therefore the ...
Can you solve this real interview question? Longest Increasing Subsequence - 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 lo
Given an unsorted array of integers, find the length of longest increasing subsequence. Example: Input: [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. Note: There may be more than one LIS combination, it i...
Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4. 1. 2. 3. Note: There may be more than one LIS combination, it is only necessary for you to return the length. Your algorithm should run in O(n2) complexity. ...

LeetCode 300. Longest Increasing Subsequence (DP) 题目 经典题目,最长递增子序列。 有O(n^2)效率,还有O(n*logn)效率的。 O(n^2)的效率很好理解的啦,就是大家最常见的那种DP O(n*logn) 的方法是维护一个递增的栈,这个栈不等于最长递增子序列。但是数组的长度一定是等于最长递增子序列的长度...
