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…

DFS + Memorized Search (DP) class Solution { int dfs(int i, int j, int row, int col, vector<vector<int>>& A, vector<vector<int>>& dp) { ) return dp[i][j]; && A[i-][j] > A[i][j]) { dp[i][j] = max(dp[i][j], dfs(i -…

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[…

Longest Increasing Subsequence 最长递增子序列 子序列不是数组中连续的数. dp表达的意思是以i结尾的最长子序列,而不是前i个数字的最长子序列. 初始化是dp所有的都为1,最终的结果是求dp所有的数值的最大值. class Solution { public: int lengthOfLIS(vector<int>& nums) { int length = nums.size(); ) ; vector<); int max_num; ;i <…

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,…
