Holiday Optimizer
Create an API wrapper around the Nager.Date API. This API allows you to retrieve all public holidays for a country in a specific year (see https://date.nager.at/Home/Api for api docs). Use this array as input for supported country codes in Nager.Date API: ["AD", "AR", "AT", "AU", "AX", "BB", "BE", "BG", "BO", "BR", "BS", "BW", "BY", "BZ", "CA", "CH", "CL", "CN", "CO", "CR", "CU", "CY", "CZ", "DE", "DK", "DO", "EC", "EE", "EG", "ES", "FI", "FO", "FR", "GA", "GB", "GD", "GL", "GR", "GT", "GY", "HN", "HR", "HT", "HU", "IE", "IM", "IS", "IT", "JE", "JM", "LI", "LS", "LT", "LU", "LV", "MA", "MC", "MD", "MG", "MK", "MT", "MX", "MZ", "NA", "NI", "NL", "NO", "NZ", "PA", "PE", "PL", "PR", "PT", "PY", "RO", "RS", "RU", "SE", "SI", "SJ", "SK", "SM", "SR", "SV", "TN", "TR", "UA", "US", "UY", "VA", "VE", "ZA"].
Requirements:
- be kind to API’s you are calling and don’t DDOS it, always throttle your requests,
- be able to handle garbage-in scenario’s
- implement in .NET Core,
- use Swagger,
- write unit tests.
Operations that should be exposed:
- Which country had the most holidays this year?
- Which month had most holidays if you compare globally?
- Which country had the most unique holidays? E.g. days that no other country had a holiday.
- Bonus question: what is the longest lasting sequence of holidays around the world you can find this year if you could travel at lightspeed between countries and timezones? o Tip: Use RestCountries.eu API to lookup timezone information per country, e.g. https://restcountries.eu/rest/v2/alpha/nl
