Maximum Alternating Sum Solution
Problem Statement
You are given an array of non-negative integers. Partition the array into 3 non-empty, non-overlapping, alternating groups such that the sum of the first group is greater than the sum of the second group. Determine the maximum sum of the groups with greater sums.
Constraints
- 1 <= resources.length <= 100
- 1 <= resources[i] <= 1000
- The number of groups is fixed at 3.
Time: O(N) Space: O(1)
Analyze constraints and compute optimal solutions step-by-step.
