Pull request overview
This PR adds a solution for the "Fresh Donuts" problem (Issue #2605), which aims to maximize the number of happy customer groups at a donut shop. A group is happy if they arrive when there's a fresh batch of donuts. The solution uses dynamic programming with memoization to optimize the arrangement of groups.
Changes:
- Implements a three-phase algorithm: counting groups with zero remainder, greedily matching complementary remainders, and using DFS with memoization to optimize remaining groups
- Includes test cases demonstrating the solution with different batch sizes and group configurations
