Explanation: The longest subsequence that is fibonacci-like: [1,2,3,5,8]. Example 2: Input: arr = [1,3,7,11,12,14,18] Output: 3 Explanation: The longest subsequence that is fibonacci-like: [1,11,12], [3,11,14] or [7,11,18]. ...
Given a strictly increasing array A of positive integers forming a sequence, find the length of the longest fibonacci-like subsequence of A. If one does not exist, return 0. (Recall that a subsequence is derived from another sequence A by deleting any number of elements (including none) from...
Return the length of the longest valid subsequence ofnums. A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements. Example 1: Input:nums = [1,2,3,4] ...

Java:https://leetcode.com/playground/VgpoWzih Time complexity: O(nlogk). Space complexity: O(k). Read More Great solution! The idea is similar tohttps://leetcode.com/problems/longest-increasing-subsequence/. However, we need to return the true sequence but not its length, if we us...
这道题给了我们两个数组A和B,让我们返回连个数组的最长重复子数组。那么如果我们将数组换成字符串,实际这道题就是求Longest Common Substring的问题了,而貌似LeetCode上并没有这种明显的要求最长相同子串的题,注意需要跟最长子序列Longest Common Subsequence区分开,关于最长子序列会在follow up中讨论。好,先来看这...
