The greatest common divisor, also known as GCD, is the greatest number that will, without a remainder, fully divide a pair of integers.

Now, I want you to make a program that will accept two integers and with the use of loops, print out their GCD. Make good use of conditional statements as well.

Off you go!

Input

A line containing two integers separated by a space.

6·9

Output

A line containing an integer.

For those of you who may not now, a factorial is a product of multiplying from 1 until the number. Now, you must make a program that will accept an integer and then print out its factorial using loops.

Are you up for this task?

Instructions:

1. Input a positive integer.
2. Using a for() loop, generate the factorial value of the integer and print out the result.
3. Tip #1: Factorials work like this: Factorial of 5 = 1 * 2 * 3 * 4 * 5
4. Tip #2: There's a special case in factorials. The factorial of 0 is 1.

Input

A line containing an integer.

5

Output

A line containing an integer.

I'm really fond of even numbers, you know? That's why I'll be letting you make another even number problem yet again. This time, you need to print from a range of two inputted numbers, n1 and n2 (inclusive), all the even numbers from n2 down to n1, in descending order.

How about that?

Input

A line containing two integers separated by a space.

3·10

Output

Multiple lines containing an integer.

As I've said before, there are three types of numbers: the positive, the zero, and the negative ones. Today, we shall pay attention only to the negative ones now. Make a loop that will accept random decimal/float numbers. When the user inputs 0, the loop will terminate and then output the sum of all negative numbers inputted in 3 decimal places.

Let's code this.

Input

Multiple lines containing a decimal .

2.4434
-1.3433
-2.444
6.432
0

Output

A line containing a decimal with three decimal places.

-3.787

Remember the game of FizzBuzz from the last time? Well, I thought of some changes in the game, and also with the help of loops as well. Firstly, you'll be asking for a random integer and then loop from 1 until that integer. Then, implement these conditions in the game:

print "Fizz" if the number is divisible by 3

print "Buzz" if the number is divisible by 5

print "FizzBuzz" if the number is divisible by both 3 and 5

print the number itself if none of the above conditions are met

Input

A line containing an integer.

Output

Multiple lines containing a string or an integer.

Let us now try comparing two numbers by letting the user input two different numbers and say "Greater" if the first inputted number is greater than the second one, and "Lesser" if it’s the other way around.

Let's go!

Input

A line containing two different numbers separated by a space.

1.2·1.02

Output

A line containing a string.
