input: Write a python function that eliminates duplicate elements from the specified tuple.  
  assert remove_duplicates((1, 3, 5, 2, 3, 5, 1, 1, 3)) == (1, 2, 3, 5)  
  assert remove_duplicates((2, 3, 4, 4, 5, 6, 6, 7, 8, 8)) == (2, 3, 4, 5, 6, 7, 8)  
  assert remove_duplicates((11, 12, 13, 11, 11, 12, 14, 13)) == (11, 12, 13, 14)
output: def remove_duplicates(t):
      return tuple(sorted(set(t)))
