+   - If the `grandTotal` is negative, an exception is thrown immediately.
    - We create a list `coinsUsed`, where each index `i` stores the most efficient combination of coins that sum up to the value `i`.
    - The list is initialized with an empty list at index `0`, as no coins are needed to achieve a total of zero.

    - After processing all values up to `grandTotal`, the combination at `coinsUsed[grandTotal]` will represent the most efficient solution.
    - If no valid combination exists for `grandTotal`, an exception is thrown.

 - **Time Complexity**: The time complexity of this approach is **O(n * m)**, where `n` is the `grandTotal` and `m` is the number of available coin denominations. This is because we iterate over all coin denominations for each amount up to `grandTotal`.
 
 - **Space Complexity**: The space complexity is **O(n)** due to the list `coinsUsed`, which stores the most efficient coin combination for each total up to `grandTotal`.
