Write a function is_even_two_digit_number that checks whether a given number is an even two-digit number.

A number is considered a two-digit number if it has exactly two digits excluding any negative sign. NOTE: This is a function type question, you don’t have to take input or print the output, just have to complete the required function definition. For example: 24 is an even two-digit number. -36 is an even two-digit number. 5 is not a two-digit number. 101 is not a two-digit number. -19 is not an even number.

Got it! You want a function is_even_two_digit_number that checks if a number is even and has exactly two digits (ignoring the negative sign).

Here’s the Python implementation:

def is_even_two_digit_number(n: int) -> bool:
    # Check if number has exactly two digits (ignoring sign)
    if 10 <= abs(n) <= 99:
        # Check if it is even
        return n % 2 == 0
    return False

✅ Explanation:
#

abs(n) makes sure negative numbers are handled (e.g., -36 → 36).
The condition 10 <= abs(n) <= 99 ensures it’s a two-digit number.
Finally, n % 2 == 0 checks if the number is even.

🔍 Examples:
#

print(is_even_two_digit_number(24))   # True
print(is_even_two_digit_number(-36))  # True
print(is_even_two_digit_number(5))    # False
print(is_even_two_digit_number(101))  # False
print(is_even_two_digit_number(-19))  # False

Would you also like me to write unit tests for this function (so you can easily validate with multiple inputs)?
