Description Input Output Sample Input 3 1 3 2 Sample Output 1 HINT 题解 由于题目要求我们求严格递增的数列,即: $$A[i]>A[i-1],1<i<=N$$ 我们不妨令B[i]=A[i]-i,那么我们容易得到 $$B[i]>=B[i-1],1<i<=N$$ 两式是等价的. 那么我们可以将原数列处理一下,我们只需要求出$B[i]$的最长不下降子序列,把不在序列中的那些数$B[i]$都改成符合条件的数(比如…

Description 给定三个正整数N.L和R,统计长度在1到N之间,元素大小都在L到R之间的单调不降序列的数量.输出答案对10^6+3取模的结果. Input 输入第一行包含一个整数T,表示数据组数. 第2到第T+1行每行包含三个整数N.L和R,N.L和R的意义如题所述. 1≤N,L,R≤10^9,1≤T≤100,输入数据保证L≤R. Output 输出包含T行,每行有一个数字,表示你所求出的答案对10^6+3取模的结果. Sample Input 2 1 4 5 2 4 5 Sample…

Given an unsorted array return whether an increasing subsequence of length 3 exists or not in the array. Formally the function should: 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…

Given an integer matrix, find the length of the longest increasing path. From each cell, you can either move to four directions: left, right, up or down. You may NOT move diagonally or move outside of the boundary (i.e. wrap-around is not allowed). E…

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…

Longest Increasing Subsequence(LIS) 一个美丽的名字 非常经典的线性结构dp [朴素]:O(n^2) d(i)=max{0,d(j) :j<i&&a[j]<a[i]}+1 直接两个for [二分查找优化]:O(n^2) g(i):d值为i的最小的a  每次更新然后lower_bound即可 ［大于等于］ lower_boundReturn iterator to lower bound Returns an iterator pointing…

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,…
