322 - Coin Change\. Medium You are given an integer array `coins` representing coins of different denominations and an integer `amount` representing a total amount of money. Return _the fewest number of coins that you need to make up that amount_. If that amount of money cannot be made up by any combination of the coins, return `-1`.
