# How will you find the minimum number of coins in change making problem?

## How will you find the minimum number of coins in change making problem?

1. coins = min(coins, result + 1); } }
2. // return the minimum number of coins needed. return coins; }
3. int main() { // coins of given denominations. vector S = { 1, 2, 3, 4 };
4. // total change required. int target = 15;

What is the minimum number of coins that must be reversed to achieve this in Java?

The Problem Assume that we are given a set of coins having the values {1, 3, 6}. To make a sum of 7 using these coins, all possible solutions are: {1,1,1,1,1,1,1}, {1,3,3}, and {1,6}. So the minimum number of coins required are 2, i.e. {1,6}.

What are the total number of combinations of the coins you can arrange to obtain 10 cents?

24 possible combinations
= 24 possible combinations. 6.

### What is coin changing problem give example?

Example 1: Suppose you are given the coins 1 cent, 5 cents, and 10 cents with N = 8 cents, what are the total number of combinations of the coins you can arrange to obtain 8 cents. Input: N=8 Coins : 1, 5, 10 Output: 2 Explanation: 1 way: 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 8 cents. 2 way: 1 + 1 + 1 + 5 = 8 cents.

What is the formula for calculating the minimum number of coins?

Find the largest denomination that is smaller than current amount. Add found denomination to result. Subtract value of found denomination from amount. If amount becomes 0, then print result.

Is coin change knapsack?

Coin change problem is very similar to unbounded knapsack problem which can be solved easily and efficiently by using Dynamic Programming. General task is to find maximum number of ways to add the coins from the array for given amount.

## What is optimal change?

Optimal change is change that happens as smoothly as it can, which means having several more ducks lined up than the well-known ADKAR® model highlights. You will have started with an optimal goal that does half of the change work for you.
