Alternating Subsequence Sum

Question

You are given an array of integers `temperatures`, find the maximum sum of an alternating subsequence where the difference between adjacent elements is either strictly increasing or strictly decreasing.

DSAMaster · Accepted Answer

To optimally solve the Alternating Subsequence Sum problem involving Arrays, it is important to analyze constraints. Time Complexity: O(n^2), Space Complexity: O(n). The optimal approach involves using dynamic programming to track the maximum sum of alternating subsequences ending at each position in the array, allowing for a more efficient solution with a time complexity of O(n^2).
