WebSo, our next task is to find the minimum number of coins needed to make the change of value n-x i.e., M n−x M n − x. Also, by choosing the coin with value x, we have already increased the total number of coins needed by 1. So, we can write: M n =1 +M n−x M n = 1 + M n − x. But the real problem is that we don't know the value of x. WebThe greedy algorithm does not always give the best answer. For instance, with 1, 6, 7, and 10 cent coins, what is the least number of coins needed to get to 13 cents? The greedy method says {10,1,1,1}, But the true answer is {7,6}. – grampa bakery and diner dania beach floridaWebHowever, this paper has a proof that if the greedy algorithm works for the first largest denom + second largest denom values, then it works for them all, and it suggests just … gram panchayat act in marathi
