还有一种稍微复杂点的方法,参见我的另一篇博客Longest Increasing Subsequence,那是 LintCode 上的题,但是有点不同的是,那道题让求的 LIS 不是严格的递增的,允许相同元素存在。 Github 同步地址: https://github.com/grandyang/leetcode/issues/300 类似题目: Increasing Trip
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,...

【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。
