Write a Python function `can_be_difference_of_squares(n)` that determines whether a given integer `n` can be represented as the difference of two squares. A number can be expressed as the difference of two squares if it is not of the form `4k + 2` for any integer `k`.
#### Function Signature
```python [main.nopy]
def can_be_difference_of_squares(n: int) -> bool:
pass
```
#### Example Usage
```python [main.nopy]
can_be_difference_of_squares(5) # True, as 5 = 3^2 - 2^2
can_be_difference_of_squares(10) # False, as 10 cannot be expressed as such
can_be_difference_of_squares(15) # True, as 15 = 8^2 - 7^2
```
#### Constraints
- The input `n` will be an integer.
- The function should return a boolean value.def can_be_difference_of_squares(n: int) -> bool:
"""
Determine if the given number can be represented as the difference of two squares.
Args:
n (int): The number to check.
Returns:
bool: True if the number can be represented as the difference of two squares, False otherwise.
