• Ensure node.js is installed
• Run npm install to install dependencies
• Run npm test to run the unit tests

Given a number , n, find the n highest and lowest scores in the given array. This task should take you no longer than 15-30 minutes.

The Net Purpose Hockey League (NPHL) is now in season! At the end of the season, the top n teams get promoted to the division above and the bottom n teams get relegated to the division below.

The division results are provided as an array of teams, as follows:

[
  {
    "name": "Rockets",
    "points": 64,
  },
  {
    "name": "Cardinals",
    "points": 77,
  },
  {
    "name": "Bruisers",
    "points": 51,
  },
  {
    "name": "Renegades",
    "points": 37,
  },
  {
    "name": "Porpoises",
    "points": 52,
  }
]

Write a function that returns a multi-line string showing the teams that will be promoted and relegated using the format below.

For an n value of 2, the results must be:

Promote:
[Highest scoring team]
[Second highest scoring team]

Relegate:
[Second lowest scoring team]
[Lowest scoring team]

For an n value of 3, the results must be:

Promote:
[Highest scoring team]
[Second highest scoring team]
[Third highest scoring team]

Relegate:
[Third lowest scoring team]
[Second lowest scoring team]
[Lowest scoring team]

There are some finished unit tests in src/index.spec.ts to get you started. There is an empty function in src/index.ts where you can write the implementation.

• There could be between 2 and 16 teams in a given division.
• A team always consists of a name string and a points integer, which is always positive or 0.
• If teams both in the top n and bottom n for the division, the promotion and relegation process will not work and the user must be notified of the problem.

• We are interested in your implementation of the solution, not the unit test code. Please feel free to add unit tests to help with development though.
• We are looking for clean code, which is easy to read and free of code smells.

When you have completed the challenge, please upload your solution to GitHub, GitLab or similar. When you have done this, please share a link with us at [email protected]. If you have any problems, we can also accept the solution attached to an email.
