coffee-machine

Write the ​working code​ to create a working coffee machine. Here are the desired features-

• It will be serving some beverages.
• Each beverage will be made using some ingredients.
• Assume time to prepare a beverage is the same for all cases.
• The quantity of ingredients used for each beverage can vary. Also, the same ingredient (ex: water) can be used for multiple beverages.
• There would be ​N​ ​( N is an integer )​ outlet from which beverages can be served. = 2 [ 2 outlets in a machine ] For N = 3 [ 3 outlets in a machine ]
• Maximum ​N​ beverages can be served in ​parallel​.
• Any beverage can be served only if all the ingredients are available in terms of quantity.
• There would be an indicator that would show which all ingredients are running low. We need some methods to refill them.
• Please provide functional integration test cases for maximum coverage.

Example​

Consider ​Chai Point ​machine which serves these drinks:

1. ginger tea
2. elaichi tea
3. coffee
4. hot milk
5. hot water

the machine has ​N​ outlets for serving these drinks Here is the composition for each drink:

1. ginger tea:

• hot water 50 ml
• hot milk 10 ml
• tea leaves syrup 10 ml - ginger syrup 5 ml
• sugar syrup 10 ml

2. elaichi tea:

• hot water 50 ml
• hot milk 10 ml
• tea leaves syrup 10 ml
• elaichi syrup 5 ml
• sugar syrup 10 ml

3. coffee:

• hot water 50 ml
• hot milk 10 ml
• coffee syrup 10 ml
• sugar syrup 10 ml

4. hot milk:

• milk 50 ml

5. hot water

• water 50 ml

Note: Since there are ​N​ outlets, ​N​ people can take beverages at the same time.

Input Test Json​ :- ​https://api.npoint.io/e8cd5a9bbd1331de326a Expected Output​ :- This input can have multiple outputs.

Output 1

hot_tea is prepared
hot_coffee is prepared
green_tea cannot be prepared because green_mixture is not available
black_tea cannot be prepared because item hot_water is not sufficient

Or

Output 2

hot_tea is prepared
black_tea is prepared
green_tea cannot be prepared because green_mixture is not available
hot_coffee cannot be prepared because item hot_water is not sufficient

Or

Output 3

hot_coffee is prepared
black_tea is prepared
green_tea cannot be prepared because green_mixture is not available
hot_tea cannot be prepared because item hot_water is not sufficient

Expectations

● To simplify the problem – we will exclude the following issues from the scope: ○ The solution does not have to scale out. We only need to design a solution to run on a single machine. ■ This machine can be assumed to have access to large high performance and reliable file systems to store the objects in. ■ This machine can be assumed to have multiple CPUs ○ The solution does not have to solve storage reliability issues (assume that the underlying file system is reliable). ● Please don’t expose any API, we need a functional test case.
