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. WebOct 25, 2016 · However, greedy doesn't work for all currencies. For example: V = {1, 3, 4} and making change for 6: Greedy gives 4 + 1 + 1 = 3 Dynamic gives 3 + 3 = 2. Therefore, greedy algorithms are a subset of dynamic programming. Technically greedy algorithms require optimal substructure AND the greedy choice while dynamic programming only …
