Question 845044: I'm having a bit of trouble figuring out the correct algorithm for this problem:
''What collection of pennies, nickels, dimes, and quarters represents the greatest total value of coins that you may have in your pocket and still not be able to make exact change for a dollar bill?''
However, I realized that I don't actually know how to do this myself without examining every possible combination of coins. There has to be a better way of solving this problem, but I don't know what the generic name for this type of algorithm would be called, and I can't figure out a way to simplify it beyond looking at every solution.
I was wondering if anybody could point me in the right direction, or offer up an algorithm that's more efficient.
