Hammerhead Interview Development Assignment

Start by forking this repo and solving the problem with completed instructions for building/running.

Open a PR against the original hammerheadnav/interview repo when you're finished.

Instructions

Write a simple program in a language of your choice that has implementations for three "services" (Strava, RWGPS, and Komoot).

Results should be printed to standard output after following the build instructions.

Services

Each service has the ability to get routes. Services can retreive all routes or retrieve routes for a specific user.

Strava

Has fixed routes ["SRT", "CVT", "Perkiomen"]
For user routes, Strava prepends the user id onto the route.

RWGPS

Has fixed routes ["CVT", "Perkiomen", "Welsh Mountain"]
For user routes, RWGPS appends the user id onto the route.

Komoot

Has fixed routes ["SRT", "Welsh Mountain", "Oaks to Philly"]
For user routes, Komoot prepends and appends the user id onto the route.

Results

The code should have the following functionality:

All Routes

Return the list of the routes across all services.

Unique Routes

Return a unique list of the routes across all services.

All User Routes

Given a user id and return a list of all the routes the user has across all services.

Users Routes by Service

Given a user id and a subset of the list of services (e.g. ["Strava", "Komoot"]) return the user's routes for only the services listed.
