Description

Given a number less than $10^{50}$, answer various questions about the number based on the line of input:

1. For Input Line #1: How many digits are in the number?
2. For Input Line #2: What is the sum of all of the digits in the number?
3. For Input Line #3: What is the sum of the digits at the odd locations? (The leftmost digit is Location #1).
4. For Input Line #4: How many times does the digit 4 appear?
5. For Input Line #5: What is the middle digit? If the length of the number, $N$, is even, find the $N/2$ number (again, the leftmost digit is the $1^{st}$ one).

Input Format

There will be 5 lines of input. Each will contain a positive integer less than $10^{50}$.

Output Format

For each line of input, print the answer to the corresponding question defined in the Description.

Explanation

Line 1: Input 1325678945. The question is "how many digits?". Counting the digits results in 10. Line 2: Input 987654. The question is "sum of all digits". $9+8+7+6+5+4 = 39$. Line 3: Input 456160. The question is "sum of digits at odd locations". Locations 1, 3, and 5 correspond to digits 4, 6, and 6. Sum = $4+6+6=16$. Line 4: Input 143295823976154. The question is "count the digit 4". The digit 4 appears twice. Line 5: Input 123456. The question is "middle digit". Length $N=6$. Since $N$ is even, we look for the $N/2 = 3^{rd}$ digit. The 3rd digit is 3.
