Coin change problem

The coin change problem is a classic computing challenge where the goal is to determine how many ways you can make a certain amount of money using a set of coins of different denominations. For instance, if you need to make $1 using coins worth 1 cent, 5 cents, and 10 cents, you want to find all possible combinations of these coins that add up to $1. This problem helps in understanding algorithms and is applicable in areas like finance, resource allocation, and optimizing supply chains, as it explores efficient ways to use given resources to achieve a target outcome.
