Sum of 1 series

Given integer 

N as input. Write a program to print the sum of series 1 + 11 + 111 + .... N terms.

Input

The first line of input is an integer N.

Output

The output should be an integer representing the sum of series.

Explanation

Given 

N = 4

The sum for first 

4 terms is 1 + 11 + 111 + 1111

So the output should be 

1234.

Number of digits until N

Given an integer 

N, write a program that prints the count of the total number of digits between 1 and N.

Input

The input is a positive integer.

Output

The output should be a single line containing the count of the digits up to the given number.

Explanation

Given 

N = 10

From 1 to 9, each number contains a single digit. From 10 onwards, the numbers contain two digits.

So the output should be 9 + 2 = 

11.

Day Name

Given day number 

D as input, write a program to display the day name.

(1 - Monday, 2 - Tuesday, 3 - Wednesday, 4 - Thursday, 5 - Friday, 6 - Saturday, 7 - Sunday)

Input

The first line of input is an integer 

D.

Output

The output should be a string representing the day name. 

Explanation

For example, if 

D = 3 then, according to the day number, the day should be Wednesday.

Compute Hypotenuse

Write a program to find the hypotenuse 

H of a right-angled triangle of sides A and B.

Note: Pythagoras theorem states that, for a right-angled triangle. Hypotenuse2 = A2 + B2

Input

The first line is an integer, 

A. The second line is an integer, B.

Output

The output should be an integer.

Explanation

In the given example, the first side 

A = 3, and the second side B = 4. To calculate the hypotenuse we use Pythagoras theorem.

According to Pythagoras theorem, hypotenuse2 = 32 + 42

Therefore, the hypotenuse value is 

5. So, the output should be 5.
