Which of the following is a motivation for passing functions around in Java?

Select one:

a. Compiled code with anonymous functions is smaller in size than with explicit functions.

(INCORRECT)b. Passing functions as objects around and applying them is significantly less complex than writing the logic for those algorithms directly.

c. It is the only way for the class to allow clients to access data that is otherwise private.

d. It allows clients to provide an algorithm without ownership of the data it operates on.

If we define a class as follows: public class Foo<T extends Bar> { }

Which of the following is a fact that we know about T? Select all that apply.

Select one or more:

a. Foo must define the same methods as Bar.

(INCORRECT)b. T must be a direct subclass of Bar.

c. T objects have access to all of the public methods defined in Bar.

d. T must be Bar or a class that inherits from Bar, directly or indirectly.

Which of the following is an advantage to using an interface as opposed to an abstract class?

Select one:

a. An interface can be the type for a variable declaration.

(INCORRECT)b. A class can inherit a default implementation for a method from an interface.

c. A class can implement multiple interfaces.

d. Interfaces can hold instance variables.

Write a program that contains a main method and another method named userName. The main method should prompt the user to enter a full name. The userName method takes the full name as an argument and prints the name in reverse order and returns the number of characters in the name. See Sample Output (input shown in blue).

PThreads

The goal of this homework is to show an understanding of pthreads and C.

Assignment:

Write a C program to use the bitwise operations with each bitwise operation contained within its own thread. Each thread should take 1 parameter and will only modify global values.

First, create global integers x and y, then, in the main function you will read in values for x and y from the user and then create the threads.

Each thread will use the parameter passed to them to determine which operation to run:

               Thread 0: |

               Thread 1: &

               Thread 2: ~

               Thread 3: ^

               Thread 4: <<

               Thread 5: >>

(You should probably use a switch statement for this)

Once a thread has computed its value (x OP y, where OP is one of the above operations, or, in the case of ~ you will just do ~x and ~y), it will then set x = y and y = (x OP y).

You will need to use a mutex to keep x and y safe when you are reading and writing this data.

In C++, please. Thank you!

Perhaps you remember the popular TV show, Deal or No Deal, with Howie Mandel as the host, that ran several years ago. In honor of the show returning in its original form (and renewed for a fifth season in 2019!) this lab is called Stack or No Stack.

As we studied in Chapter 1, imagine again a bag data structure into which we can insert and remove elements. This bag has two operations, defined as:

This time the bag is somewhat mysterious. Given a sequence of inserts and removals, the bag may operate like a LIFO stack, or it may not.

Your program must guess whether or not the bag is operating as a stack given a series of operations and the corresponding return values.

Program Input

The input to your program will be a series of test cases in a file. Each test case begins with a line containing a single integer n (1 < n < 100). Following the operations defined in the above table, each of of the next n lines is either a type-1 command followed by an integer x (which inserts the value x) or a type-2 command followed by an integer x which means the command retrieves the value x. The value of x is always a positive integer not larger than 100. There will be no ambiguous test cases. In other words, you will be able to fully determine the output based on the input alone. The input is terminated by an end-of-file (EOF).  

Your code may use anything in the standard C++ library -- including the STL stack container. This is, of course, optional.

Program Output

For each test case, output one of the following:

stack
not stack

which will indicate whether or not the bag is determined to be operating as a stack, given the series of operations.

What to Submit

Please submit a .cpp file which contains your solution to the problem. Your program should take its input from a file. You will want to write some test driver code but you are not required to submit it as part of the assignment Do so only if it is convenient.

How to Earn Full Credit

Your code should compile, run, and pass all of the below test cases.

Code that does not compile or pass at least the below test cases will have points deducted. Your professor has held back a few extra cases that your program must also pass to receive full credit. Your program should output only 'stack' or 'not stack' once per line, with one line for each test case.

Sample Input

Create a file with the following lines and use it as input into your program. Please use at least these as your test cases before submitting your code in Canvas.

Q4. Tiger Woods is known for having one of the fastest driving swings in Golf (among other things). In fact, his Tee-off ball speed was recorded to be 122 MPH.

1. Determine what Tiger Wood’s angular velocity and acceleration are for the club. He is 1.85 meters tall. (Refer to the Anthropometry slides to estimate his shoulder height)

Shoulder height = 1.5133

122 MPH = 54.54 m/s

4. The DuPont System allows us to relate the return on total assets and the return on common equity to various measures of firm characteristics. Consider a firm with a ROA of 0.04.
a. If you were analyzing a firm that had sales of $12500 and total assets of $10000, how much in earnings were available for common shareholders?

b.If the firm had common stockholders' equity of $3300, what would be the firm's ROE?

c. If we compare this firm to another similar firm in the industry we find that the comparison firm has an ROA and ROE of 0.05 and 0.191663, respectively. Given this information, calculate the comparison firm's ratio of total assets to common stock equity. How does this ratio differ from our firm?

d.Interpret the performance differences between these firms.

Where does the soft drink, Fanta, fit on the BCG portfolio management matrix in the Coca-Cola Company? Would it be considered a "star" with high relative market share and high market growth rate? A "cash cow" with high relative market share and low market growth rate? A "question mark" with low relative market share and high market growth rate? Or a "dog" with low relative market share and low market growth rate?

For reference:

Dogs. Dogs hold low market share compared to competitors and operate in a slowly growing market. In general, they are not worth investing in because they generate low or negative cash returns. But this is not always the truth. Some dogs may be profitable for long period of time, they may provide synergies for other brands or SBUs or simple act as a defense to counter competitors moves. Therefore, it is always important to perform deeper analysis of each brand or SBU to make sure they are not worth investing in or have to be divested.
Strategic choices: Retrenchment, divestiture, liquidation

Cash cows. Cash cows are the most profitable brands and should be “milked” to provide as much cash as possible. The cash gained from “cows” should be invested into stars to support their further growth. According to growth-share matrix, corporates should not invest into cash cows to induce growth but only to support them so they can maintain their current market share. Again, this is not always the truth. Cash cows are usually large corporations or SBUs that are capable of innovating new products or processes, which may become new stars. If there would be no support for cash cows, they would not be capable of such innovations.
Strategic choices: Product development, diversification, divestiture, retrenchment

Stars. Stars operate in high growth industries and maintain high market share. Stars are both cash generators and cash users. They are the primary units in which the company should invest its money, because stars are expected to become cash cows and generate positive cash flows. Yet, not all stars become cash flows. This is especially true in rapidly changing industries, where new innovative products can soon be outcompeted by new technological advancements, so a star instead of becoming a cash cow, becomes a dog.
Strategic choices: Vertical integration, horizontal integration, market penetration, market development, product development

Question marks. Question marks are the brands that require much closer consideration. They hold low market share in fast growing markets consuming large amount of cash and incurring losses. It has potential to gain market share and become a star, which would later become cash cow. Question marks do not always succeed and even after large amount of investments they struggle to gain market share and eventually become dogs. Therefore, they require very close consideration to decide if they are worth investing in or not.
Strategic choices: Market penetration, market development, product development, divestiture

Two independent companies, Bayer and Monsanto are in the chemical and pharmaceutical industries. Each owns a piece of laboratory equipment used in research and development of new products, but each would like the other firm’s equipment. They agree to exchange the equipment. An appraiser was hired, and from her report and the companies' records, the following information was obtained: Bayer’s Equipment Monsanto's Equipment Cost $826,000 $460,000 Accumulated depreciation $250,000 $100,000 Fair value based upon appraisal $720,000 $630,000 The exchange was made and based on the difference in appraised fair values. Monsanto paid $90,000 to Bayer.
