This project implements rest services in order to resolve the max change-making problem.

It provides REST services in order to:

  • insert coins e.g. insert 2 coins of value 1 POST /api/Coins { amount: 1, quantity: 2 }
  • change coin e.g. request change for an amount of 2 POST /api/ChangeCoins { amount: 2 }
  • retrieve result of change coin e.g. with previous response {id} from ChangeCoin resource GET /api/ChangeCoins/{id}/coins And example of returned result:
{"amount":1,"quantity":-2,"id":2,"coinId":1,"coinChangeId":1}

    { \"amount\": 2, \"quantity\": 1 },
    { \"amount\": 3, \"quantity\": 1 },
    { \"amount\": 4, \"quantity\": 1 },
    { \"amount\": 5, \"quantity\": 1 }

[{"amount":1,"quantity":1,"id":1},{"amount":2,"quantity":1,"id":2},{"amount":3,"quantity":1,"id":3},{"amount":4,"quantity":1,"id":4},{"amount":5,"quantity":1,"id":5}]

Ask for some Coin Change. Example below request change for 8.

[{"amount":1,"quantity":-1,"id":6,"coinId":1,"coinChangeId":1},{"amount":3,"quantity":-1,"id":7,"coinId":3,"coinChangeId":1},{"amount":4,"quantity":-1,"id":8,"coinId":4,"coinChangeId":1}]
