Python binary_search_recur Examples

Example #1

 def test_binary_search(self):
     array = [1, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 6]
     self.assertEqual(10, binary_search(array, 5))
     self.assertEqual(11, binary_search(array, 6))
     self.assertEqual(None, binary_search(array, 7))
     self.assertEqual(None, binary_search(array, -1))
     # Test binary_search_recur
     self.assertEqual(10, binary_search_recur(array, 0, 11, 5))
     self.assertEqual(11, binary_search_recur(array, 0, 11, 6))
     self.assertEqual(-1, binary_search_recur(array, 0, 11, 7))
     self.assertEqual(-1, binary_search_recur(array, 0, 11, -1))
