最长上升公共子序列(Longest Increasing Common Subsequence,LICS)也是经典DP问题,是LCS与LIS的混合. Problem 求数列 a[1..n], b[1..m]的LICS的长度, a[], b[]数组的元素均为正整数. Solution 考虑如何定义DP状态,定义DP状态就是定义所谓的最优子问题(optimal subproblem),而DP状态要能转移,就是所谓最优子问题要具有重叠子结构. 将DP状态定义为 DP[i][j]:a[1..i], b[…
Give an integer array,find the longest increasing continuous subsequence in this array. An increasing continuous subsequence: Can be from right to left or from left to right. Indices of the integers in the subsequence should be continuous. Notice O(n…

LintCode 397: Longest Increasing Continuous Subsequence 题目描述 给定一个整数数组(下标从0到n - 1,n表示整个数组的规模),请找出该数组中的最长上升连续子序列.(最长上升连续子序列可以定义为从右到左或从左到右的序列.) 样例 给定[5, 4, 2, 1, 3], 其最长上升连续子序列(LICS)为[5, 4, 2, 1], 返回4. 给定[5, 1, 2, 3, 4], 其最长上升连续子序列(LICS)为[1, 2, 3, 4], 返…

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 length is 4. Note that there may be more th…
[抄题]: 往上走台阶 最长上升子序列问题是在一个无序的给定序列中找到一个尽可能长的由低到高排列的子序列,这种子序列不一定是连续的或者唯一的. 样例 给出 [5,4,1,2,3],LIS 是 [1,2,3],返回 3给出 [4,2,4,5,3,7],LIS 是 [2,4,5,7],返回 4   [思维问题]: 不知道怎么处理递增:还是坐标型(有小人在里面跳),用i j来进行比较 intialization answer都不止一个点:可以从所有的点开始或结束 [一句话思路]: [输入量]:空: 正…
一.题目描述 Given a sequence A = < a1, a2, -, am >, let sequence B = < b1, b2, -, bk > be a subsequence of A if there exists a strictly increasing sequence ( i1 < i2 < i3 -, ik ) of indices of A such that for all j = 1,2,-,k, aij = bj. For ex…
