Solution: Make Your own Change Machine

Explore the implementation of a greedy algorithm to make change using Java. Understand how to select coins starting from the largest denomination, iterating until the amount is reduced to zero. This lesson breaks down the code step-by-step and discusses the time complexity of the approach, helping you grasp how greedy solutions work in optimization problems.

Solution: The greedy way

The simple greedy idea is to start from the largest possible coin available (in our case, it is a quarterquarter, or 25 cents ...
