What features should you be looking for selecting routers, switches, and servers?

The Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21…… starts with two 1s, and each term afterward is the sum of its two predecessors. Please write a function, Fib(n), which takes n as the input parameter. It will return the n-th number in the Fibonacci sequence. Using R, the output for Fib(9) should give only the 9th element in the sequence and not any of the previous elements. Please Help :)

The program must prompt for an integer divisor in the range 10-20 and will print all numbers 1-1000 that are divisible by that divisor. You MUST use a while loop for this. Use printf to display the numbers in right-aligned columns, 10 to a line. For example, “%5d” would be the format String to allow a field width of 5 to display the number. If the number entered by the user is out of range just print an error message. (Java)

IMPORTANT : For this exercise, you will be defining a function that USES the Stack ADT. A stack implementation is provided to you as part of this exercise - you should not use your own Stack class. Instead, simply use the functions: Stack(), push(), pop() and is_empty() where necessary inside your function definition.

For this exercise, you must write a function called balanced_brackets(). This function will be passed a string as an input, and you must check that any parentheses or angled brackets in the string, that is: '(', '<', ')' and '>', are correctly balanced.

Here are a few examples of strings where brackets are correctly balanced:

a(<bcd>ef)g 
abcde 
a(b)c<<d>e(fg)>

and here are a few examples where the brackets are not balanced:

ab(cde> 
a<bc>)def<g> 
ab)c

Your balanced_brackets() function should return True if the input string is balanced, and False otherwise. Remember, you can assume that an implementation of the Stack ADT is available to you. It is therefore likely that your function definition will begin as follows:

def balanced_brackets(text):  
    s = Stack()  
    ...

For example:

print(balanced_brackets('(<x>)(())()'))

True

print(balanced_brackets('x(y)z'))

True

# Write a function called `get_state_data` that allows you to specify a state,
# then saves a .csv file (`STATE_data.csv`) with observations from that state
# This includes data about the state, as well as the counties in the state
# You should use the full any.drinking dataset in this function (not just 2012)

# Demonstrate that you function works by passing "Utah" to the function
state_Utah <- get_state_data(Utah)

############################ Binge drinking Dataset ############################

# In this section, you will ask a variety of questions regarding the
# `binge_drinking.csv` dataset. More specifically, you will analyze a subset of
# the observations of *just the counties* (exclude state/national estimates!).
# You will store your answers in a *named list*, and at the end of the section,
# Convert that list to a data frame, and write the data frame to a .csv file.
# Pay close attention to the *names* to be used in the list.

# Create a dataframe with only the county level observations from the
# `binge_driking.csv` dataset. You should (again) think of Washington D.C. as
# a state, and therefore *exclude it here*.
# However, you should include "county-like" areas such as parishes and boroughs
county_data <- binge.drinking.csv %>% distinct(state)

# Create an empty list in which to store answers to the questions below.

# What is the average county level of binge drinking in 2012 for both sexes?
# Store the number in your list as `avg_both_sexes`.

# What is the name of the county with the largest increase in male binge
# drinking between 2002 and 2012?
# Store the county name in your list as `largest_male_increase`.

# How many counties experienced an increase in male binge drinking between
# 2002 and 2012?
# Store the number in your list as `num_male_increase`.

# What fraction of counties experienced an increase in male binge drinking
# between 2002 and 2012?
# Store the fraction (num/total) in your list as `frac_male_increase`.

  
# How many counties experienced an increase in female binge drinking between
# 2002 and 2012?
# Store the number in your list as `num_female_increase`.

# What fraction of counties experienced an increase in female binge drinking
# between 2002 and 2012?
# Store the fraction (num/total) in your list as `frac_female_increase`.

# How many counties experienced a rise in female binge drinking *and*
# a decline in male binge drinking?
# Store the number in your list as `num_f_increase_m_decrease`.

# Convert your list to a data frame, and write the results
# to the file `binge_info.csv`

# The next questions return *data frames as results*:

# What is the *minimum* level of binge drinking in each state in 2012 for
# both sexes (across the counties)? Your answer should contain roughly 50 values
# (one for each state), unless there are two counties in a state with the
# same value. Your answer should be a *dataframe* with the location, state, and
# 2012 binge drinking rate. Write this to a file called `min_binge.csv`.

# What is the *maximum* level of binge drinking in each state in 2012 for
# both sexes (across the counties)? Your answer should contain roughly 50 values
# (one for each state), unless there are two counties in a state with the
# same value. Your answer should be a *dataframe* with the location, state, and
# 2012 binge drinking rate. Write this to a file called `max_binge.csv`.

  
################################# Joining Data #################################
# You'll often have to join different datasets together in order to ask more
# involved questions of your dataset. In order to join our datasets together,
# you'll have to rename their columns to differentiate them.

# First, rename all prevalence columns in the any_drinking dataset to the
# have prefix "any_" (i.e., `males_2002` should now be `any_males_2002`)
# Hint: you can get (and set!) column names using the colnames function.
# This may take multiple lines of code.

# Then, rename all prevalence columns in the binge_drinking dataset to the have
# the prefix "binge_" (i.e., `males_2002` should now be `binge_males_2002`)
# This may take multiple lines of code.

# Then, create a dataframe by joining together the both datasets.
# Think carefully about the *type* of join you want to do, and what the
# *identifying columns* are. You will use this (joined) data to answer the
# questions below.

# Create a column `diff_2012` storing the difference between `any` and `binge`
# drinking for both sexes in 2012

# Which location has the greatest *absolute* difference between `any` and
# `binge` drinking? Your answer should be a one row data frame with the state,
# location, and column of interest (diff_2012).
# Write this dataframe to `biggest_abs_diff_2012.csv`.

# Which location has the smallest *absolute* difference between `any` and
# `binge` drinking? Your answer should be a one row data frame with the state,
# location, and column of interest (diff_2012).
# Write this dataframe to `smallest_abs_diff_2012.csv`.

############## Write a function to ask your own question(s) ####################
# Even in an entry level data analyst role, people are expected to come up with
# their own questions of interest (not just answer the questions that other
# people have). For this section, you should *write a function* that allows you
# to ask the same question on different subsets of data. For example, you may
# want to ask about the highest/lowest drinking level given a state or year.
# The purpose of your function should be evident given the input parameters and
# function name. After writing your function, *demonstrate* that the function
# works by passing in different parameters to your function.

################################### Challenge ##################################

# Using your function from part 1 that wrote a .csv file given a state name,
# write a separate file for each of the 51 states (including Washington D.C.)
# The challenge is to do this in a *single line of (very concise) code*

# Write a function that allows you to pass in a *dataframe* (i.e., in the format
# of binge_drinking or any_drinking) *year*, and *state* of interest. The
# function should saves a .csv file with observations from that state's counties
# (and the state itself). It should only write the columns `state`, `location`,
# and data from the specified year. Before writing the .csv file, you should
# *sort* the data.frame in descending order by the both_sexes drinking rate in
# the specified year. The file name should have the format:
# `DRINKING_STATE_YEAR.csv` (i.e. `any_Utah_2005.csv`).
# To write this function, you will either have to use a combination of dplyr
# and base R, or confront how dplyr uses *non-standard evaluation*
# Hint: https://github.com/tidyverse/dplyr/blob/34423af89703b0772d59edcd0f3485295b629ab0/vignettes/nse.Rmd
# Hint: https://www.r-bloggers.com/non-standard-evaluation-and-standard-evaluation-in-dplyr/

# Create the file `binge_Colorado_2007.csv` using your function.

Create a UI that has a field in which to enter text, a field to display read-only text and a button. When the button is pressed, take the value of the text box and try to create a month object. If a number was entered, use the constructor that accepts an integer. If alphabetic characters were entered, use the constructor that accepts a string. If nothing is entered, use the no-argument constructor. If a valid month object is created, use the toString function on the month object to display info about the month. Otherwise, display an appropriate error message.

Create a UI with two drop-down lists, a button, and a field to display read-only text. One drop-down has the values 1-12. The other has the names of the months. When the button is pressed, create two-month objects using the appropriate constructors, then display if the months are equal, if month 1 > month 2 or if month 2 > month 1.

TWO SEPERATE USER INTERFACES.

THIS IS TO BE DONE USING JAVA

Prepare functional specifications for my barbershop company the Web and the internet. Include links to and from other sites in your design.

Implement a simple banking system in Java. Your application should demonstrate the following. Upon running the java code, first the application should welcome the user, then ask the user to give one of the options:

1) display the balance summary,

2) withdraw money, or

3) deposit money.

Based on the options your code should perform the following operations such as

1) read the transaction details from a file and display them on the screen.

2) ask the user to enter the amount he wants to withdraw and debit the withdrawal amount from the balance amount. It has to update the file and display the transaction summary. The system should not allow an attempt to withdraw an amount greater than the balance.

3) ask the user to enter the amount he wants to deposit, credit the balance and update the file. It should display the transaction summary.

The records in the file should contain transaction number, transaction type, amount withdrawn, or amount deposited, and balance. Example:

1 Deposit 100.0$ 1100.0$

2 Withdraw 50.0$ 1050.0$

The welcome screen should look like:

Welcome to CIS-2348 Banking System!

Enter your Option in a number: 1. Display balance 2. Deposit amount 3. Withdraw amount We assume that there is an opening balance of 1000 available in the system (Assign balance=1000.0 in the beginning of the code). Also, while running first start by choosing deposit option or withdraw option.

Write a C++ program named, myGrade.cpp, that calculates a letter grade for a student of this course (CSC100 online) based on three user inputs. This program should begin by printing the title of the application (program) and a brief description of what it does. (Note: this is NOT the same as the program prolog: a prolog is much more detailed, has required elements, and is intended for other programmers reading the cpp file. The title and description displayed by the program are meant for the user of the program.)

Next, the program must prompt the user for three integer inputs in the following order: 1) Points earned on programming assignments, 2) Points earned on MPL homework, and 3) Points earned on the final exam. Each prompt should be clear, concise, and free of spelling errors. After getting all three of the integer inputs, the program should either print an input validation error message and then terminate or output the required data for this program.

If an input error is detected, one and only one of the following error messages should be displayed:

1. The number of points entered for Programming Assignments must be between 0 and 400, inclusive.
2. The number of points entered for MPL Homework must be between 0 and 200, inclusive.
3. The number of points entered for the Final Exam must be between 0 and 400, inclusive.

After displaying one of these error messages, the program should terminate after displaying:
myGrade is now terminating.

Only if there is no input error would the program continue normal execution. This means that the next step after all three inputs are validated is to make the necessary calculations and determinations to display the following items of information to the user in this order:

1. The number of Programming Assignment points entered
2. The number of MPL Homework points entered
3. The number of Final Exam points entered
4. The total number of points earned
5. The student's letter grade
6. A support message based on the letter grade earned

Each numeric value displayed should be preceded by a clear, concise label stating what the number means. The total points earned is the sum of the three integers input by the user. The letter grade is determined by matching the total points to the correct row in the table given under the Grading section in the Syllabus. Your code will need to implement efficient grade range checks to determine the appropriate letter grade based on the table in the syllabus. Use named constants for the grade range boundaries (900, 800, etc.) and store the determined letter grade as an upper case letter in variable of type, char. Do not use any variables of type, double, in this program: double is not needed since all entries are integers and the grade range boundaries are integers. Your program must also implement the course rule that automatically assigns a letter grade of F when the Final Exam points earned are less then 240, i.e., 60% of the total possible.

Your program must use a switch statement on the letter grade (type, char) to print one and only one of the following support messages:

1. For an A, print:      Great job! You will have no problem in CSC205.
2. For a B, print:        Good job! You should have little trouble in CSC205.
3. For a C, print:        Ok, you passed, but you may be challenged in CSC205.
4. For a D, print:       When you retake this course, you will be able to do much better.
5. For an F, print either:
             You did not put forth enough effort to pass this course.
   or
             You did not score enough points on the Final Exam to pass this course.

Once all six items of information are displayed (in the order listed above), the program should terminate after displaying:

myGrade is now terminating.

TRUE for THIS and ALL programs submitted in this course:
Avoid unnecessary point deductions by formatting your code AND following ALL pertinent coding conventions. Make sure all requirements are implemented. Make sure the program does not calculate or display anything that is NOT required. Remember named constants.

Example of Output:

Example output from your program if the three inputs were: 305 (programming assignments), 108 (MPL Homework), and 288 (Final Exam):

Programming Assignment points entered: 305
MPL Homework points entered           108
Final Exam points entered:            288
Total number of points earned:          701           
Student's letter grade earned:        C

MPL Homework points entered         200
Final Exam points entered:            239
Total number of points earned:      839           
Student's letter grade earned:            F
     You did not score enough points on the Final Exam to pass this course.

Final Exam points entered:            240
Total number of points earned:      595           
Student's letter grade earned:            F
     You did not put forth enough effort to pass this course.

Example output from your program if the three inputs were: -348 (programming assignments), 139 (MPL Homework), and 300 (Final Exam):

Programming Assignment points entered: -348
MPL Homework points entered           139
Final Exam points entered:              300
The number of points entered for the Programming Assignments must be between 0 and 400, inclusive.

Assignment Description

Write a program that will have a user guess whether a person is a musician or a writer. You will create a

group of four names, two musicians and two writers, and show the user a name randomly selected from

the four. The user will then guess whether they think the name belongs to a musician or writer. After a

guess, the program will tell the user whether they are correct, repeat the name, and reveal the correct

answer.

Tasks

1) The program needs to contain the following

a.

A comment header containing your name and a brief description of the program

b. At least 5 comments besides the comment header explaining what your code does

c.

Four string variables, two musicians and two writers

d. A way to randomly display one of the four names to the user

e. Output asking the user whether the name displayed is a musician or a writer

i. If the user guesses correctly, congratulate them before outputting the displayed

name and the correct answer

ii. If the user guesses incorrectly, output the displayed name and the correct

answer

f.

“Press enter to continue” and Console.Read(); at the end of your code

2) Upload the completed .cs file onto the Assignment 3 submission folder. To access the .cs file:

a.

Right click on your program tab

b. Click “Open containing folder”

c.

The file you are working on will be there with a .cs extention, upload the .cs file

In this assignment, you will implement Breadth First Search (BFS). The input to your program is a graph in the adjacency list format. The input graph has at most 100 vertices. Your program must initiate a BFS from vertex 2 of the graph. If the graph is connected, your program must output “Graph is connected”. If the graph is disconnected, your program must output “Graph is not connected”. Your program should read from an input file: data2.txt and write to the output file: out2.txt.

Your program should be written in C or C++. You can use STL for a queue but not for a graph.
