PROBLEM:
You’re given a number, you have to find out whether it is multiple of 2,4 and 8.
EXPLANATION:
For a number to be multiple of 2,4 and 8, it should be divisible by 8.
For a number to be multiple of 8, the last three digits of that number must be divisible by 8.
If the number of digits in a particular number is less than three then the whole number must be divisible by 8.
