Description

This PR adds an implementation of the Coin Change Algorithm using Dynamic Programming in Python.
It efficiently computes the minimum number of coins required to make a given amount using a bottom-up DP approach.

Example

# Example usage
coins = [1, 2, 5]
amount = 11
print(coin_change(coins, amount))  # Output: 3

Hi maintainers

I’ve added a Dynamic Programming solution for the Coin Change Problem under dynamic_programming/coin_change.py.
The code follows the project guidelines, includes proper docstrings, and passes local tests.

Please review when convenient
Thank you for maintaining such a great educational repo!
