Given

Json fixtures file with recipe data. Download Link

Important notes

1. Property value "delivery" always has the following format: "{weekday} {h}AM - {h}PM", i.e. "Monday 9AM - 5PM"
2. The number of distinct postcodes is lower than 1M, one postcode is not longer than 10 chars.
3. The number of distinct recipe names is lower than 2K, one recipe name is not longer than 100 chars.

Functional Requirements

1. Count the number of unique recipe names.
2. Count the number of occurences for each unique recipe name (alphabetically ordered by recipe name).
3. Find the postcode with most delivered recipes.
4. Count the number of deliveries to postcode 10120 that lie within the delivery time between 10AM and 3PM, examples (12AM denotes midnight):
   • NO - 9AM - 2PM
   • YES - 10AM - 2PM
5. List the recipe names (alphabetically ordered) that contain in their name one of the following words:
   • Potato
   • Veggie
   • Mushroom

Non-functional Requirements

1. The application is packaged with Docker.
2. Setup scripts are provided.
3. The submission is provided as a CLI application.
4. The expected output is rendered to stdout. Make sure to render only the final json. If you need to print additional info or debug, pipe it to stderr.
5. It should be possible to (implementation is up to you):
   a. provide a custom fixtures file as input
   b. provide custom recipe names to search by (functional reqs. 5)
   c. provide custom postcode and time window for search (functional reqs. 4)

Expected output

Generate a JSON file of the following format:

{
    "unique_recipe_count": 15,
    "count_per_recipe": [
        {
            "recipe": "Mediterranean Baked Veggies",
            "count": 1
        },
        {
            "recipe": "Speedy Steak Fajitas",
            "count": 1
        },
        {
            "recipe": "Tex-Mex Tilapia",
            "count": 3
        }
    ],
    "busiest_postcode": {
        "postcode": "10120",
        "delivery_count": 1000
    },
    "count_per_postcode_and_time": {
        "postcode": "10120",
        "from": "11AM",
        "to": "3PM",
        "delivery_count": 500
    },
    "match_by_name": [
        "Mediterranean Baked Veggies", "Speedy Steak Fajitas", "Tex-Mex Tilapia"
    ]
}
