Holiday planner

Definition

You are planning your next holiday for 2020, and want to know what is the best time to take it in terms of maximizing the length of the time away while minimizing your annual leave balance with your current employer.

Build a simple interface where the user can input the duration of the holiday (in number of days) and the system should provide you with the best option(s) for 2020.

Example 1: duration of holiday is 4 days.
2 best options: 
- 10/04/2020 to 13/04/2020 (0 days of annual leave)
- 25/12/2020 to 28/12/2020 (0 days of annual leave)

Example 2: duration of holiday is 5 days.
4 best options: 
- 09/04/2020 to 13/04/2020 (1 day of annual leave)
- 10/04/2020 to 14/04/2020 (1 day of annual leave)
- 24/12/2020 to 28/12/2020 (1 day of annual leave)
- 25/12/2020 to 29/12/2020 (1 day of annual leave)

Additional instructions

  • Keep it simple, i.e. UI-wise a simple number input for the holiday duration with a list of options (see example below) is enough.
  • Preferably use the Kynd FrontEnd Stack with consists of VueJS, vue-cli, Vuex, Apollo (http://apollo.vuejs.org/), Typescript and moment.
  • Share a repository with your code or send a it over, with brief instruction and documentation on how to run it locally.
  • This should take about 4 hours, if you get stuck on the algorithm for the optimization of days or you don't get it exactly right, don't stress about it: we can go through and sort it out during the review.
  • This could help for the algo part: https://codility.com/media/train/13-CaterpillarMethod.pdf, although a purely naive implementation is fine too (performance is not a consideration for the purpose of this exercise).

GraphQL

Use the playground there : https://lfym1mly5f.execute-api.us-east-2.amazonaws.com/dev/graphql. This documents the endpoint.

There, you can type and execute the following query :

query {
  publicHolidays(jurisdictions: [QLD]) {
    date
    name
    day
    description
    jurisdiction
  }
}

Which should give the following output:

{
  "data": {
    "publicHolidays": [
      {
        "date": "2020-01-01T00:00:00.000Z",
