WebJun 6, 2015 · Divide the problem into two parts: (1) a function to compute the number of coins needed to achieve a given total. Here it is: coins = (5,3,1) # order this list max to min def coin_count (x): n = 0 for a_coin in coins: count = x // a_coin n += count x -= a_coin * count return n. (2) You simply call this function to generate any desired output. The second design flaw is that the greedy algorithm isn't optimal for some instances of the coin change problem. The code has an example of that. When amount is 20 and the coins are [15,10,1], the greedy algorithm will select six coins: 15,1,1,1,1,1 when the optimal answer is two coins: 10,10.
