Problem 42406. Divisible by 4
Pursuant to the first problem in this series, this one involves checking for divisibility by 4.
Write a function to determine if a number is divisible by 4. This can be checked by a few slightly different methods:
- Check the last two digits for divisibility by four.
- From the wikipedia reference page: "If the tens digit is even, the ones digit must be 0, 4, or 8. If the tens digit is odd, the ones digit must be 2 or 6."
- Check the following sum for divisibility by four: twice the tens digit plus the ones digit.
Previous problem: divisible by 3. Next problem: divisible by 5.
