Calculate the Area and Perimeter for shapes using functions in Python.

Your goal is to match the sample output below:

Welcome to my area and perimeter calculator
======================================================
Circle   : area = 39.82, perimeter = 22.37
Square   : area = 85.19, perimeter = 36.92
Rectangle: area = 41.24, perimeter = 34.24
Triangle : area = 21.16

Here is the code to use for your program (Note you may have to type this code into Trinket directly)

Open two windows in Ubuntu, and list the content of the /dev/fd folder. Can you explain the difference observed from the two windows? The name /dev/fd is actually a symbolic link to /proc/self/fd. The name self is also a symbolic link pointing to a number, which is the process ID of the current process. Therefore, the number pointed to by self is different if viewing from different windows.

Use the following format for each of your files in the header.

# Name:

# Description:

You programs should be FULLY COMMENTED.

1. Mr. Zapanta has locked himself out of his laptop and completely forgotten his password (the password is “cardinalcarter123” or “CardinalCarter123”). Write a program that generates a password entry. The program will display an appropriate message if Mr. Zapanta enters the wrong password. The program will allow a maximum of 5 tries to enter. If he exceeds 5 tries, the program will stop and display “Your laptop has been locked”. (5 marks Thinking) (Use a while loop)

Sample Output 1:

Enter the password: mr. zapanta

That is not the correct password! Try again.

Enter the password: cardinal carter

That is not the correct password! Try again.

Enter the password: ilovecompsci

That is not the correct password! Try again.

Enter the password: carter123

That is not the correct password! Try again.

Enter the password: chicken321!

That is not the correct password! You’ve reached the max number of tries.

Your laptop has been locked.

Sample Output 2:

Enter the password: mr. zapanta

That is not the correct password! Try again.

Enter the password: cardinalcarter123

Welcome, Mr. Zapanta.

Consider an n-node complete binary tree T, where n = 2d − 1 for some d. Each node v of T is labeled with a real number xv. You may assume that the real numbers labeling the nodes are all distinct. A node v of T is a local minimum if the label xv is less than the label xw for all nodes w that are joined to v by an edge.
You are given such a complete binary tree T, but the labeling is only specified in the following implicit way: for each node v, you can determine the value of xv by probing the node v. Show how to find a local minimum of T using only O(logn) probes to the nodes of T.

This question concerns writing a Student class to model a student's name, composed
of a first name, middle name and last name. The Student class should meet the
following specification:

2
Thinking of the problem in terms of testing, there are three requirements that must be
met:
1. The setNames() method sets the names stored in the object i.e. the values of
firstName, middleName, lastName.
2. The getFullName() method obtains the name of the student with the middle name
converted to an initial only.
3. The getFullName() method does not change anything – i.e. it does not modify the
values of firstName, middleName, lastName
HINT: To start your Student class, we suggest using the following instance variables:
Instance variables
private String firstName;
private String middleName;
private String lastName;
In order to test the requirement above create a java class called StudentTest that allows
the user to enter the first name, middle name and last name. These values must be set
using the created set meothod and afterwards displays the information back to the
console, however the Middle name is an initial ONLY

Complete Answer Must Compile in Visual Code in template Form Code, Must Reflect in UI.

1.            Add a new text box - Mavenlink Project Name

2.            Once we enter project name and project code , on tab change Mavenlink Project Name should be set as

Project Code - Project Name

Example :

Project Code =   T1002

Project Name =   TEST123

So in this case Mavenlink Project Name will be T1002 - TEST123

Write a program that does the following in order:

1. Asks the user to enter a name

2. Asks the user to enter a number “gross income”

3. Asks the user to enter a number “state tax rate”

4. Calculates the “Federal Tax”, “FICA tax” and “State tax”

5. Calculates the “estimated tax” and round the value to 2 decimal places

6. Prints values for “name”, “gross income” and “estimated tax”

The program should contain three additional variables to store the Federal tax, FICA tax, State tax, gross income, and estimated tax.

Federal Tax = gross income * 9.45%

FICA Tax = gross income * 7.65%

State Tax = gross income * your state tax percent

Estimated Tax = Federal tax + FICA tax + State tax

NOTE: Percentages must be converted to decimal values, for example:

15.9%=15.9*0.01=0.159

An example of the program’s input and output is shown below:

Enter your name: Belinda Patton

Enter your gross income: 53398.12

Enter your state income tax rate: 4.27

Tony Johnbull estimated tax is $11411.08 based on a gross income of $53398.12

1-Using the Note class and make it Comparable. A Note is larger than another note if it is higher in frequency. 2-In the driver program create a few objects and compare them . then create a list of those objects and sort them. 3. Rewrite the Note class so that a list of Notes is sorted first by length of note, then within that by frequency.

The UA record app can provide personalised advices to a specific user by collecting and analysing personal data. Please list one example for each of the following data types, categorical, ordinal and numerical, in the context of the case study. [5 marks]

2.       The UA Record app collects the data from a lot of users, and thereby the backend system can do trend analysis over these data. However, the data could be collected through different versions of different devices and apps, in different countries, at real time by sensors or manually. What kind of data quality issues do you think there could exist? Please list at least three different data quality issues and briefly explain them. [5 marks]

Discuss how you would set up control measures in your organization or even your home? What considerations must you include in your risk analysis? How do those differ when analyzing risk for hardware, software, and cloud services?

Situation (Data Structures and Sorting C++)
You have been employed at BmoCel, an internet service provider. Data is sent as packets from their
server to their clients. Each packet has a fixed size of 16 alphanumeric characters. However, they are
currently having problems with managing their data transmissions. Your bosses have asked you to
rectify the problem

The client manages the packets in a First‐In, First‐Out manner. Due to transmission limitations of the client, only 8 packets can be transmitted in the transmission pipeline at any given time. If another packet is to be transmitted, the first packet that was transmitted will be stored onto the client, making room for additional packets in the transmission pipeline.

To create a home budget, you want to find out your net income, which is your income minus your expenses.

Write a Java method that takes an input string and computes the income minus the expenses.
The income components are indicated by numbers; while the expenses from your spending are numbers starting with a minus sign '-'.



The input string may contain lowercase and uppercase letters, as well as other characters.

Note that Character.isDigit(char) tests if a char is one of the chars '0', '1', ..., '9'. Also recall that Integer.parseInt(string) converts a string to an int.

Test cases :
calcNetIncome("salary 15000yuan bonus2000 rent -1000Y") → 16000
calcNetIncome("25000 gross income, -200 water, electricity:-300") → 24500
