--description--

Given a ski hill's vertical drop, horizontal distance, and type, determine the difficulty rating of the hill.

To determine the rating:

  • Calculate the steepness of the hill by taking the drop divided by the distance.
  • Then, calculate the adjusted steepness based on the hill type:
    • "Downhill": multiply steepness by 1.2
    • "Slalom": multiply steepness by 0.9
    • "Giant Slalom": multiply steepness by 1.0

Return:

  • "Green" if the adjusted steepness is less than or equal to 0.1
  • "Blue" if the adjusted steepness is greater than 0.1 and less than or equal to 0.25
  • "Black" if the adjusted steepness is greater than 0.25

--hints--

get_hill_rating(95, 900, "Slalom") should return "Green".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(95, 900, "Slalom"), "Green")`)
}})

get_hill_rating(620, 2800, "Downhill") should return "Black".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(620, 2800, "Downhill"), "Black")`)
}})

get_hill_rating(420, 1680, "Giant Slalom") should return "Blue".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(420, 1680, "Giant Slalom"), "Blue")`)
}})

get_hill_rating(250, 3000, "Downhill") should return "Green".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(250, 3000, "Downhill"), "Green")`)
}})

get_hill_rating(110, 900, "Slalom") should return "Blue".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(110, 900, "Slalom"), "Blue")`)
}})

get_hill_rating(380, 1500, "Giant Slalom") should return "Black".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_hill_rating(380, 1500, "Giant Slalom"), "Black")`)
}})
