Problem 4. (7 points) Implementation: Implement the make change algorithm you designed in the previous problem. Your program should read a text file "data.txt" where each line in "data.txt" contains three values c, k and n. Please make sure you take your input in the specified order c, k and n. For example, a line in "data.txt" may look like the following: 3 4 38 where c= 3, k = 4, n = 38. That is, the set of denominations is {30, 31, 32, 33, 34} = {1,3,9, 27,81}, and we would like to make change for n = 38. The file "data.txt" may include multiple lines like above. The output will be written to a file called "change.txt", where the output corresponding to each input line contains a few lines. Each line has two numbers, where the first number denotes a de- nomination and the second number represents the cardinality of that denomination in the solution. For example, for the above input line '3 4 38', the optimal solution is the multiset {27,9,1,1), and the output in the file "change.txt" is as follows: 27 1 91 12 which means the solution contains 1 coin of denomination 27, one coin of 9 and two coins of denomination 1. You can use a delimiter line to separate the outputs generated for different input lines. Makes change using a recursive Greedy algorithm. @param amount The amount of change to make. @param coins The sorted set of coins, ordered from smallest to largest. * @return The number of coins used to make the change. int makeChangeGreedy Style (int amount, int[] coins) { // Check if there is no more change to make. if (amount == 0) { System.out.println(""); return 0; // Loop over the change in order of greatest to smallest. for (int i = coins.length; i > 0; i--) { int coin = coinsi - 1]; // If the next largest coin is found, print out its value. if (amount >= coin) { System.out.print(coin + " "); return 1 + make change GreedyStyle(amount - coin, coins); // Arriving here means it's impossible to make change // using this greedy algorithm, this amount of change, // and this set of coins. System.out.print("Cannot make change; "); System.out.println("cents remaining: " + amount); return 0; Problem 4.
