WebApr 7, 2024 · Find the coin change (Greedy Algorithm) when coins are in decimals and returned amount in coins is larger then original return value. Ask Question Asked 2 years ago. Modified 2 years ago. Viewed 388 times 0 I need to find the number of coins that make a given value where coins are in decimals and there is a possibility that the algorithm … WebThe Coin Change Problem makes use of the Greedy Algorithm in the following manner: Find the biggest coin that is less than the given total amount. Add the coin to the result and subtract it from the total amount to get the pending amount. If the pending amount is zero, print the result. Else, repeat the mentioned steps till the pending amount ...
WebAug 19, 2015 · Follow the steps below to implement the idea: Declare a vector that store the coins. while n is greater than 0 iterate through greater to smaller coins: if n is greater than equal to 2000 than push 2000 into the vector and decrement its value from n. else if n is … 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!). Fortunately, computer science has given cashiers everywhere ways to minimize numbers of coins due: greedy algorithms.
