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}. – 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. iris motion sensor v2
