3202. Find the Maximum Length of Valid Subsequence II

LeetCodeArrayDynamic ProgrammingOpen on judge ↗

You are given an integer array nums and a positive integer k. A subsequence sub of nums with length x is called valid if it satisfies: - (sub[0] + sub[1]) % k == (sub[1] + sub[2]) % k == ... == (sub[x - 2] + sub[x - 1]) % k. Return the length of the longest valid subsequence of nums. Example 1: Input: nums = [1,2,3,4,5], k = 2 Output: 5 Explanation: The longest valid subsequence is [1, 2,
