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 length is 4. Note that there may be more than…

Given a sequence of integers, find the longest increasing subsequence (LIS). You code should return the length of the LIS. Have you met this question in a real interview?     Example For [5, 4, 1, 2, 3], the LIS  is [1, 2, 3], return 3 For [4, 2, 4,…

最长公共子序列 英文缩写为LCS(Longest Common Subsequence).其定义是,一个序列 S ,如果分别是两个或多个已知序列的子序列,且是所有符合此条件序列中最长的,则 S 称为已知序列的最长公共子序列.而最长公共子串(要求连续)和最长公共子序列是不同的 应用 最长公共子序列是一个十分实用的问题,它可以描述两段文字之间的“相似度”,即它们的雷同程度,从而能够用来辨别抄袭.对一段文字进行修改之后,计算改动前后文字的最长公共子序列,将除此子序列外的部分提取出来,这种方法判断修改的…

题目描述 作为一名情报局特工,Nova君(2号)有着特殊的传达情报的技巧.为了避免被窃取情报,每次传达时,他都会发出两句旁人看来意义不明话,实际上暗号已经暗含其中.解密的方法很简单,分别从两句话里删掉任意多个字母,使得两句话剩余的部分相同,通过一定的删除手法,可以让剩余的部分相同且长度最大,就得到了可能的暗号.暗号可能有多个,还要进行筛选,现在情报局人手不够,希望你能助一臂之力,筛选工作不用你完成,你只需计算出暗号长度以及个数即可.(注意,字母的位置也是暗号的重要信息,位置不同的字母组成的暗号不…

给出一个无序的整形数组,找到最长上升子序列的长度.例如,给出 [10, 9, 2, 5, 3, 7, 101, 18],最长的上升子序列是 [2, 3, 7, 101],因此它的长度是4.因为可能会有超过一种的最长上升子序列的组合,因此你只需要输出对应的长度即可.你的算法的时间复杂度应该在 O(n2) 之内.进阶: 你能将算法的时间复杂度降低到 O(n log n) 吗? 详见:https://leetcode.com/problems/longest-increasing-subsequenc…

最长公共子序列(LCS)是一个在一个序列集合中(通常为两个序列)用来查找所有序列中最长子序列的问题.这与查找最长公共子串的问题不同的地方是:子序列不需要在原序列中占用连续的位置 .最长公共子序列问题是一个经典的计算机科学问题,也是数据比较程序,比如Diff工具,和生物信息学应用的基础.它也被广泛地应用在版本控制,比如Git用来调和文件之间的改变. 最长公共子串问题是寻找两个或多个已知字符串最长的子串.此问题与最长公共子序列问题的区别在于子序列不必是连续的,而子串却必须是连续的. 定义:一个数列,…
