What do you mean by making change problem in algorithm?
The change making problem is an optimization problem that asks “What is the minimum number of coins I need to make up a specific total?” The input to the Change Making Problem is a sequence of positive integers [d1, d2, d3 dn] and T , where di represents a coin denomination and T is the target amount.

Is there an optimal solution to the making change problem?
On the other hand Dynamic Programming is guaranteed to give an optimal solution so let us get started. Given a set of coin denominations (V1 = 1, V2, V3, …, Vn) and an amount of money (C). Make change for the given amount of money using a minimum number of coins.
How to solve the change making problem using dynamic programming?
This is a C++ Program that Solves Change Making Problem using Dynamic Programming technique. There are infinite number of coins of n different values. These values are given. Using these coins, you have to make change for Rs. Sum. Find the minimum number of coins required to change Rs. Sum.
What is the problem of the change making problem?
The change making problem is an optimization problem that asks “What is the minimum number of coins I need to make up a specific total?”. The input to the Change Making Problem is a sequence of positive integers [d1, d2, d3 dn] and T, where di represents a coin denomination and T is the target amount.
How do you solve the coin change problem?
The idea is to use recursionto solve this problem. We recur to see if the total can be reached by including the coin or not for each coin of given denominations. If choosing the current coin resulted in the solution, update the minimum number of coins needed. Finally, return the minimum value we get after exhausting all combinations.
