Mathematical formula for arithmetic progression is. Longest arithmetic progression in a sorted array Problem: Given a sorted array, find the longest arithmetic progression in the same. The longest bitonic subarray problem is to find a subarray of a given sequence in which the subarray's elements are first sorted in in increasing order, then in decreasing order, and the subarray is as long as possible. For the first example, the subarray {5, 3, 1, 4, 2} when sorted can form a continuous sequence 1,2,3,4,5, which are the longest. Longest Arithmetic Subsequence of Given Difference.

Question: Given an array A, try to find the longest increasing sub-sequence (the sub-sequence do not need to be adjacent). Arithmetic progression is set of numbers in which difference between two consecutive numbers is constant. Among other things, the code is also easier to test now. New [Java] Clean code beats 100% with explanation. I have an array of numbers ex. Longest arithmetic progression means an increasing sequence with common difference, in this case [2,4,6,8]. Example 1: Input: arr = [1,2,3,4], difference = 1 Output: 4 Explanation: The longest arithmetic subsequence is [1,2,3,4].
