**QUESTION:**

Create a **function** called **binary_converter**. Inside the function, implement an algorithm to convert decimal numbers between **0 and 255** to their binary equivalents.

For any invalid input, return string Invalid input

Example: For number **5** return string **101**

**TEST CASE:**

```
import unittest
class BinaryConverterTestCases(unittest.TestCase):
def test_conversion_one(self):
result = binary_converter(0)
self.assertEqual(result, '0', msg='Invalid conversion')
def test_conversion_two(self):
result = binary_converter(62)
self.assertEqual(result, '111110', msg='Invalid conversion')
def test_no_negative_numbers(self):
result = binary_converter(-1)
self.assertEqual(result, 'Invalid input', msg='Input below 0 not allowed')
def test_no_numbers_above_255(self):
result = binary_converter(300)
self.assertEqual(result, 'Invalid input', msg='Input above 255 not allowed')
```
