What is the main idea behind the dynamic programming approach to the Coin Change Problem?

Step 1: Understand the Coin Change Problem. It involves finding the minimum number of coins needed to make a certain amount of money using given coin denominations.
Step 2: Recognize that dynamic programming is a method used to solve problems by breaking them down into simpler subproblems and storing the results of these subproblems to avoid redundant calculations.
Step 3: Identify the base case. For example, if the amount is 0, you need 0 coins.
Step 4: Create an array (or table) to store the minimum number of coins needed for each amount from 0 to the target amount.
Step 5: Fill in the array by iterating through each coin and updating the minimum number of coins needed for each amount that can be formed using that coin.
Step 6: The final value in the array for the target amount will give you the minimum number of coins needed.
