input: Write a function to generate a set of unique random numbers in the range 0-10 using Python. The function should return the set of numbers. If the range is less than or equal to the number of desired random numbers, it should return an empty set.
  assert generate_random_numbers(5) != {}
  assert generate_random_numbers(10) != {}
  assert generate_random_numbers(11) == {}
  assert generate_random_numbers(0) == {}
output: def generate_random_numbers(n):
      if n > 10:
          return set()
      import random
      return set(random.sample(range(11), n))
