# 10209. Play with digits

## I'm a slow walker, but I never walk backwards.

We have a huge decimal number. Write a program to compute the following answers:

• The number of digits.
• 1 if it is even; 0 otherwise.
• The number of zeros in digits.
• 1 if it is divided by 11; 0 otherwise.

We will give you the number digit by digit in lines. If you get digits ‘1’, ‘2’, ‘3’, ’4’, ‘0’ in order, then the decimal number is 12340.

## Input Format

The input has several lines. Each line has a digit. EOF indicates the end of input.

## Output Format

Output the answer above line by line.

• 10 points: you can store the decimal number in an integer without overflow
• 10 points: the number of digits is no more than 32768, so you can store digits in an array
• 80 points: you will get MLE if you use array

## Sample Input 1
