Given US denomination coins, what is the algorithm to make change for any amount?

3 Answers

Greedy algorithm will work in this case

Code is in JAVA : public class USCoins { public static void main(String args[]) { int[] coinDenominations = {25,10,5,1}; double totalAmountInDollars = 3.46; int[] numberOfEachCoin = getNumber(coinDenominations,totalAmountInDollars); for(int number : numberOfEachCoin) System.out.println(number); } private static int[] getNumber(int[] coinDenominations, double totalAmountInDollars) { int numberOfEachCoin[] = new int[coinDenominations.length]; int totalAmountInCents = (int) (totalAmountInDollars*100); for(int i=0;i<coinDenominations.length;i++) { int denomination = coinDenominations[i]; numberOfEachCoin[i] = totalAmountInCents/denomination; totalAmountInCents = totalAmountInCents%denomination; } return numberOfEachCoin; } }

Inspired by this problem, I have proposed a solution that print out all possible change combinations per given amount. I demo the problem solving process in this video: http://www.youtube.com/watch?v=3VBjhiKUtmE

The "unexpected" factor came in the generalized form of the "case" question. As best I can remember, the question was a hypothetical about a large federal client engaging the firm to optimize their IT portfolio. Almost no details were specified, and subsequent questions in response to the ideas I offered did not provide many particular parameters to consider.
