Suppose we need to make change for n cents, and we want to use the least number of coins of denominations 1, 10, and 25 cents. consider the following greedy strategy: suppose the amount left to change is m. take the largest coin that is no more than m, subtract this coin’s value from m, and repeat. prove that this algorithm is optimal, or give a counterexample if it is not.
