Note that even if all values are negative, I don't have an option to Problem: We have to find the maximum sum of elements in an array containing positive numbers such that no 2 adjacent elements are included. Maximum sum of non-adjacent elements Problem You are given an array/list of ‘N’ integers. Example 1: Input: N = 6 Arr[] = {5, 5, 10, 100, 10, 5} Output: Apr 11, 2024 · Given an array arr[] of distinct Integers, find the pair with maximum sum such that both elements of the pair are not adjacent in the array Examples: Input: arr[] = {7, 3, 4, 1, 8, 9}Output: 9 7Explanation: Pair with maximum sum is (8, 9). Mar 10, 2024 · In the max_sum_non_adjacent() function, we employ a dynamic programming strategy to construct an array ‘dp’ that holds the maximum non-adjacent sum up to that index. HackerRank Problem Link May 27, 2017 · Find Complete Code at GeeksforGeeks Article: http://www. It is possible that the maximum sum is , the case when all elements are negative. Please note that the problem specifically targets subsequences that need not be contiguous, i. Note that these elements are non-adjacent. But, explanation is just explanation, I guess we should focus on the real question. Maximum Sum of Subsequence With Non-adjacent Elements - LeetCode Apr 20, 2018 · I came across this question.
