What coins do you need to make any amount of change?
So what is the fewest number of coins you can carry that allows you to produce any exact change? The answer is 10 coins, 3 Quarters, 1 dime, 2 nickel, and 4 pennies. With this combination you can produce any number between 1-99 cents.
What is the greatest possible value of all the coins in the 12 bags?
What is the greatest possible value of all the coins in the 12 bags? correct answer = 1615 dollar.
What is coin change problem?
From Wikipedia, the free encyclopedia. The change-making problem addresses the question of finding the minimum number of coins (of certain denominations) that add up to a given amount of money. It is a special case of the integer knapsack problem, and has applications wider than just currency.
What’s the minimum number of coins to make the change?
Total amount is 13 and we have coins with values 1, 4 and 5. Since, we are to find minimum number of coins and we have infinite number of coin for any denomination, it’s apparent that we would go for greedy.
Is there an algorithm to find minimum number of coins?
For example, it doesn’t work for denominations {9, 6, 5, 1} and V = 11. The above approach would print 9, 1 and 1. But we can use 2 denominations 5 and 6. Thanks to Utkarsh for providing the above solution here.
What’s the minimum number of coins to make V cents?
Given a value V, if we want to make change for V cents, and we have infinite supply of each of C = { C1, C2, .. , Cm} valued coins, what is the minimum number of coins to make the change? If it’s not possible to make change, print -1. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution.
How to calculate the total amount of coins?
You are given coins of different denominations and a total amount of money amount. Write a function to compute the fewest number of coins that you need to make up that amount. If that amount of money cannot be made up by any combination of the coins, return -1. coins = [2], amount = 3, return -1.
