Define a function check_out_of_boundaries that receives a number and returns
True if it is greater than 10 OR less than 0 and False otherwise.

Examples:

>>> check_out_of_boundaries(7)
False
>>> check_out_of_boundaries(12)
True
>>> check_out_of_boundaries(-3)
True
import unittest


class CheckOutOfBoundariesTestCase(unittest.TestCase):

    def test_negative(self):
        self.assertEqual(check_out_of_boundaries(-3), True)

    def test_over_10(self):
        self.assertEqual(check_out_of_boundaries(12), True)

    def test_in_boundaries(self):
        self.assertEqual(check_out_of_boundaries(7), False)
