- Finds the minimum number of coins needed to make a target amount. Uses dynamic programming with both top-down and bottom-up approaches. Handles edge cases including impossible amounts and zero target. Prints DP table, coin combinations, and optimal solutions. Time Complexity: O(amount * num_coins).
- Space Complexity: O(amount) for DP array.

Pull Request Overview
This PR implements the classic Coin Change algorithm in R using dynamic programming to find the minimum number of coins needed to make a target amount. The implementation includes comprehensive documentation, edge case handling, and example test cases.
- Implements dynamic programming solution with O(amount * num_coins) time complexity
- Includes helper function for visualizing the DP table for educational purposes
- Provides three test cases covering basic usage, impossible amounts, and larger datasets
