"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. " - Greedy algorithm coin change
