input: Write a function to generate a set of unique random numbers in the range 0-10 using Python. If the range of numbers is less than 10, return an empty set.
  assert generate_unique_random_numbers() == {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
  assert generate_unique_random_numbers() == set()
  assert generate_unique_random_numbers() == set()
  assert generate_unique_random_numbers() == set()
  assert generate_unique_random_numbers() == set()
output: import random
