### Operating a robot

We are operating a robot. The robot can move in four directions only: North, East, West, and South. Each move is specified as a direction and a number of steps.

### The task

Using Spring Boot (or any other web framework you choose), implement a simple web service in Java with two endpoints. The application should store the input data and the corresponding result for each request in a database. You can use any data access library/framework and database to implement the service.

Don’t forget to commit your changes as you usually do when implementing such a project. Feel free to use any IDE features and follow any standard development practices.

*Optional*: Add 1-2 unit tests to cover simple cases. 

The web service endpoints should implement the following functionality:

1. Receives a list of movement operations in JSON format as an input and outputs the coordinates recorded after each move as a JSON document. Assume that the initial location for the robot is always at (0, 0).

   Example of a curl command to test your implementation:

   

   ```bash

   curl --header "Content-Type: application/json" \

   --request POST \

   --data '[{"direction":"EAST","steps":1},{"direction":"NORTH","steps":3},{"direction":"EAST","steps":3},

            {"direction":"SOUTH","steps":5},{"direction":"WEST","steps":2}]' \

   http://localhost:8080/locations

   ```

   

   Result:

   ```json

   [{"x":0,"y":0},{"x":1,"y":0},{"x":1,"y":3},{"x":4,"y":3},{"x":4,"y":-2},{"x":2,"y":-2}]

   ```

2. Receives a list of locations and outputs a list of robot moves to visit all locations. Assume that the starting location of the robot is the first in the input list.

   Example of a curl command to test your implementation:

   

   ```bash

   curl --header "Content-Type: application/json" \

     --request POST \

     --data '[{"x": 0, "y": 0}, {"x": 1, "y": 0}, {"x": 1, "y": 3}, {"x": 0, "y": 3}, {"x": 0, "y": 0}]' \

     http://localhost:8080/moves

   ```

   

   Result:

   ```json

   [{"direction":"EAST","steps":1},{"direction":"NORTH","steps":3},{"direction":"WEST","steps":1},{"direction":"SOUTH","steps":3}]

   ```

* *Optional*: Find the shortest path through all of the locations provided as an input.

* *Note*: For testing you could also use commands from [requests.http](requests.http)
