Greedy change making algorithm

WebChange-Making Suppose you need to “make change” with the fewest number of coins possible. Is the greedy algorithm optimal if you have 1 cent coins, 10 cent coins, and 15 cent coins? What about for U.S. coinage (1, 5, 10, 25, 50, 100) Take the biggest coin less than the change remaining. Introduce yourselves! If you can turn your video on ... WebGreedy Algorithms. When making change, odds are you want to minimize the number of coins you’re dispensing for each customer, lest you run out (or annoy the customer!). …

Making A Change Problem With the Greedy Approach

WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem.
