--description--

Given a snowboarder's starting stance and a rotation in degrees, determine their landing stance.

• A snowboarder's stance is either "Regular" or "Goofy".
• Trick rotations are multiples of 90 degrees. Positive indicates clockwise rotation, and negative indicate counter-clockwise rotation.
• The landing stance flips every 180 degrees of rotation.

For example, given "Regular" and 90, return "Regular". Given "Regular" and 180 degrees, return "Goofy".

--hints--

get_landing_stance("Regular", 90) should return "Regular".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Regular", 90), "Regular")`)
}})

get_landing_stance("Regular", 180) should return "Goofy".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Regular", 180), "Goofy")`)
}})

get_landing_stance("Goofy", -270) should return "Regular".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Goofy", -270), "Regular")`)
}})

get_landing_stance("Regular", 2340) should return "Goofy".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Regular", 2340), "Goofy")`)
}})

get_landing_stance("Goofy", 2160) should return "Goofy".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Goofy", 2160), "Goofy")`)
}})

get_landing_stance("Goofy", -540) should return "Regular".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Goofy", -540), "Regular")`)
}})

get_landing_stance("Goofy", 90) should return "Goofy".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_landing_stance("Goofy", 90), "Goofy")`)
}})
