Coin Change, Part 2

May 21, 2013

In the previous exercise we studied the classic coin change problem to find all the ways to make a given amount of change using a given set of coins. Sometimes the problem in a different way: find the minimum set of coins needed to make a given amount of change. As with the prior exercise, sometimes the task is to find just the count and sometimes the task is to find the actual set of coins.

Your task is to write the two programs described above. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
