[Stage 27] Even Digits Only

Check if all digits of the given integer are even.

Example

• For n = 248622, the output should be evenDigitsOnly(n) = true;
• For n = 642386, the output should be evenDigitsOnly(n) = false.

Input/Output

• [execution time limit] 4 seconds (py3)

• [input] integer n

Guaranteed constraints: 1 ≤ n ≤ 109.

[output] boolean

true if all digits of n are even, false otherwise.

def evenDigitsOnly(n):
    while n > 0:
        if not n % 2 == 0:
            return False
        else:
            n //= 10
    return True
