Change
Correctly determine the fewest number of coins to be given to a customer such that the sum of the coins' value would equal the correct amount of change.
For example
 An input of 15 with [1, 5, 10, 25, 100] should return one nickel (5) and one dime (10) or [0, 1, 1, 0, 0]
 An input of 40 with [1, 5, 10, 25, 100] should return one nickel (5) and one dime (10) and one quarter (25) or [0, 1, 1, 1, 0]
Edge cases
 Does your algorithm work for any given set of coins?
 Can you ask for negative change?
 Can you ask for a change value smaller than the smallest coin value?
