给定一个未排序的数组,请判断这个数组中是否存在长度为3的递增的子序列.正式的数学表达如下:    如果存在这样的 i, j, k,  且满足 0 ≤ i < j < k ≤ n-1,    使得 arr[i] < arr[j] < arr[k] ,返回 true ; 否则返回 false .要求算法时间复杂度为O(n),空间复杂度为O(1) .示例:输入 [1, 2, 3, 4, 5],输出 true.输入 [5, 4, 3, 2, 1],输出 false. 详见:https://…

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[…

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…
这个题是说看一个没有排序的数组里面有没有三个递增的子序列,也即: Return true if there exists i, j, k such that arr[i] < arr[j] < arr[k] given 0 ≤ i < j < k ≤ n-1 else return false. 大家都知道这个题有很多解法,然而题主丧心病狂地说要O(n)的时间复杂度和O(1)的空间复杂度. 我当时考虑的是找三个递增的数,中间那个数比较重要,所以我们可以遍历该数组,检查每个元素是不是…
Given strings S and T, find the minimum (contiguous) substring W of S, so that T is a subsequence of W. If there is no such window in S that covers all characters in T, return the empty string "". If there are multiple such minimum-length window…
