Eg: {1,3,5}, {1,2,3} are arithmetic subsequence of sequence {1,2,3,4,5} with length 3. how to construct any permutation of first N positive integers such that the length of the longest arithmetic subsequence of the permutation is equal to K. Iterating the array, and record the intermediate answers in a hash map - this requires O(N) time and O(N) space. You are given integers \(n\) and \(k\) . The element order in the arithmetic sequence should be same as the element order in the array. An arithmetic subsequence of sequence \(A\) is a subsequence of \(A\), that is an arithmetic progression. … This is the brute force approach that I came up with. {0, 8, 4, 12, 2, 10, 6, 14, 1, 9, 5, 13, 3, 11, 7, 15} Output: The length of longest increasing subsequence. Give the length 4 as the output. Here's the Problem. A subsequence slice of that array is any sequence of integers like (K0, K1, K2, … Kn) such that 0 <= K0 < K1 < K2 < … < Kn < N. A subsequence slice (K0, K1, K2, … Kn) of A is called arithmetic slice, if the sequence A[K0], A[K1], … A[Kn] is arithmetic, so this means that n >= 2. 分析.
