for i in displayList:

4. Negative Fusion

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.

-1.3433

-2.444

6.432

Output

A line containing a decimal with three decimal places.

-3.787

3. The Last 'Zeroes'

How many zeroes are there after the last non-zero digit of a million? A trillion? To easily identify that, let us make a program to count and print the number of zeroes after the last non-zero digit on a number. For example, in 20400, there are 2 zeroes after the last non-zero digit of the number, 4.

Are you up for this challenge?

Input

A line containing an integer.

20400

Output

A line containing an integer.

2. Phonics

Did you know that the first letters in the alphabet that a child learns are the vowels? Well, since they're the first letters that we learned as babies, then they must be easy to identify, right? So, let's make a code that will identify all vowels in a string and print out how many they are!

Let's go!

Input

A line containing a string.

Output

A line containing an integer.

1. FizzBuzz 2.0

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.

This problem is related to the virtual learning environment application discussed in one theory session and a few practicals. In this problem, you are tasked with creating and updating learner profiles, a particular type of user. As well, given a learner profile, we would like to retrieve the learning materials in the form of topics. Note that the learning materials for a given course will differ from one learner profile to another. For example, for a course "Distributed Systems and Applications", the learning materials for a learner with a weak background in "Programming" compared o another learner profile with a stronger background in programming.

Your task is to:

1. Provide a description in OpenAPI of the API that allows for communication between a client and a service for the functionalities discussed above;

2. Implement a corresponding client and a service. 

Output should include: 

• This assignment uses 1 loop
• It will require that you use escape characters like \n.
• Please note that the sales tax in PA is 6%
• Make sure that the program does not ask for price again once a user decides to checkout.
