WebJun 2, 2024 · For example, 1000000 // 15 is 66666 and 1000000 % 15 is 10. The second design flaw is that the greedy algorithm isn't optimal for some instances of the coin change problem. The code has an example of that. When amount is 20 and the coins are [15,10,1], the greedy algorithm will select six coins: 15,1,1,1,1,1 when the optimal … WebOct 15, 2024 · And to print it, you just go: System.out.println ("Total coins needed: " +coinChangeGreedy (coins, n)); Additionally - if you want to keep track of coins used, you can store them in an ArrayList every time it is chosen. list.add (coins [i]). And of course you declare and initialize that list` at the beggining.

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.
