In this programming project, you will be implementing the data structure min-heap. You should use the C++ programming language, not any other programming language. Also, your program should be based on the g++ compiler on general.asu.edu. All programs will be compiled and graded on general.asu.edu, a Linux based machine. If you program does not work on that machine, you will receive no credit for this assignment. You will need to submit it electronically at the blackboard, in one zip file, named CSE310-P02-Lname-Fname, where Lname is your last name and Fname is your first name. The zip file should contain a set of files that are absolutely necessary to compile and execute your program. If you program does not compile on general.asu.edu, you will receive 0 on this project.
You need to define the following data types.
ELEMENT is a data type that contains a field named key, which is of type int. In later assignments, you will have to add on other fields to ELEMENT, without having to change the functions. Note that ELEMENT should not be of type int.
HEAP is a data type that contains three fields named capacity (of type int), size (of type int), and H (an array of type ELEMENT with index ranging from 0 to capacity).
The functions that you are required to implement are
Initialize(n) which returns an object of type HEAP with capacity n and size 0.
BuildHeap(heap, A), where heap is a HEAP object and A is an array of type ELEMENT. This function copies the elements in A into heap->H and uses the linear time build heap algorithm to obtain a heap of size size(A).
Insert(heap, k) which inserts an element with key equal to k into the min-heap heap.
DeleteMin(heap) which deletes the element with minimum key and returns it to the caller.
DecreaseKey(heap, element, value) which decreases the key field of element to value, if the latter is not larger than the former. Note that you have make necessary adjustment to make sure that heap order is maintained.
printHeap(heap) which prints out the heap information, including capacity, size, and the key fields of the elements in the array with index going from 1 to size.
1
You should implement a main function which takes the following commands from the key-board:
•S •Cn •R •W •Ik •D •Kiv
On reading S, the program stops.
On reading C n, the program creates an empty heap with capacity equal to n, and waits for the next command.
On reading R, the program reads in the array A from file HEAPinput.txt, calls the linear time build heap algorithm to build the heap based on A, and waits for the next command.
On reading W, the program writes the current heap information to the screen, and waits for the next command.
On reading I k, the program inserts an element with key equal to k into the current heap, and waits for the next command.
On reading D, the program deletes the minimum element from the heap and prints the key field of the deleted element on the screen, it waits for the next command.
On reading K i v, the program decreases the key of element with index i to the new value v, pro- vided that the new value is not larger than the previous value.
The file HEAPinput.txt is a text file. The first line of the file contains an integer n, which in- dicates the number of array elements. The next n lines contains n integers, one integer per line. These integers are the key values of the n array elements, from the first element to the nth element.
You should use modular design. At the minimum, you should have • the main program as main.cpp and the corresponding main.h;
• the heap functions heap.cpp and the corresponding heap.h;
2
• various utility functions util.cpp and the corresponding util.h.
You should also provide a Makefile which compile the files into an executable file named run. Grading policies: (Sample test cases will be posted soon.)
(10 pts)
(10 pts) (10 pts) (10 pts) (10 pts) (10 pts) (10 pts) (10 pts) (10 pts) (10 pts)
Documentation: You should provide sufficient comment about the variables and algorithms. You also need to provide a README file describing which language you are using. You will also need to provide a Makefile. The executable file should be named run.
Data types: You should define the required data types. Initialize
BuildHeap
Insert
DeleteMin DecreaseKey printHeap modular design Makefile
Above all, you need to write a working program to correctly parse the commands specified in the project. Without this, your program will not be graded.

Pointers: Single size allocation heap has issues w/ deallocation because a heap variable can be pointed to by various pointers so when one is deallocated doesn't necessarily mean the memory is free to be marked available again. What are methods of keeping track of garbage collection? (hint:

Answers

Methods of keeping track of garbage collection include reference counting, mark and sweep, copying, generational and incremental.

There are several methods for keeping track of garbage collection in a heap with single size allocation. Some common methods include:

Reference counting: This method keeps track of the number of references to each heap object. When the reference count drops to zero, the object is considered garbage and can be deallocated.

Mark and sweep: This method involves marking all reachable objects, then sweeping through the heap and deallocating any objects that were not marked.

Copying: This method involves copying all reachable objects to a new heap, then deallocating the old heap. This method can be more memory-efficient than mark and sweep, but requires more copying.

Generational: This method involves dividing the heap into multiple generations, with newer objects in one generation and older objects in another. Garbage collection is performed more frequently on the younger generation, with less frequent garbage collection on the older generation.

Incremental: This method involves breaking up the garbage collection process into smaller, incremental steps that can be performed between program execution. This can help reduce the impact of garbage collection on program performance.

Each method has its own advantages and disadvantages, and the best method depends on the specific needs of the program and the constraints of the system.

insert the following letters into an empty b-tree of order 5 in the order given: box in your final b-tree. h o t q b f x j d s g z i r e v c k w a

Answers

The final B-tree would look like this:

```
              q
       /      |      \
  h o t    b f   j x  r
        \ / \ / \ / | / \
        d g i k w a box v c e s z
```

To insert the given letters into an empty B-tree of order 5, we start by creating a root node with the first letter "h". Since the order is 5, we can insert up to 4 more letters in the root node. Next, we insert "o", "t", and "q" in the root node in the order given.

Now the root node is full, so we split it and move the middle value "q" up to a new root node. The left node contains "h", "o", and "t", and the right node contains "b", "f", "x", "j", "d", "s", "g", "z", "i", "r", "e", "v", "c", "k", "w", and "a".

We can now insert "box" into the B-tree. Starting at the root node, we compare "b" with "q" and follow the left child pointer since "b" is less than "q". In the left node, we compare "b" with "h" and follow the left child pointer since "b" is less than "h". In the leftmost node, we can insert "b" since there is room.

Next, we compare "o" with "q" and follow the right child pointer since "o" is greater than "h" but less than "q". In the right node, we compare "o" with "f" and follow the right child pointer since "o" is greater than "f". In the second rightmost node, we can insert "o" since there is room.

Next, we compare "x" with "q" and follow the right child pointer since "x" is greater than "q". In the right node, we compare "x" with "r" and follow the left child pointer since "x" is less than "r". In the second leftmost node, we can insert "x" since there is room.

Finally, we compare "box" with "q" and follow the right child pointer since "box" is greater than "q". In the right node, we compare "box" with "r" and follow the right child pointer since "box" is greater than "r". In the rightmost node, we can insert "box" since there is room.

The final B-tree would look like this:

```
              q

a profit-maximizing firm will hire workers up to the quantity of labor at which: group of answer choices mrpl > w. mrpl

Answers

A profit-maximizing firm will hire workers up to the quantity of labor at which the marginal revenue product of labor (MRPL) is equal to the wage (W). In other words, the firm will hire workers until MRPL = W.

A profit-maximizing firm will hire workers until MRPL = W. This can be explained as follows :

1. The firm aims to maximize profits by comparing the additional revenue generated by hiring an extra worker (MRPL) to the cost of hiring that worker (W).
2. If MRPL > W, the firm can increase profits by hiring more workers, as the additional revenue generated is greater than the wage paid.
3. If MRPL < W, the firm should reduce the number of workers, as the cost of hiring a worker is greater than the additional revenue generated.

Number Filter Write a program that will filter a list of non-negative integers such that all duplicate values are removed. Integer values will come from standard input (the keyboard) and will range in value from 0 up to 2,000,000,000. Input will be terminated by the special value, -1. Once the input is read in you should output (to the screen) the list of numbers as a sorted list (smallest to largest) with one value listed per line where all duplicates have been removed. The primary difficulty with this program is that there are an enormous number of input values and an expected large number of duplicate numbers. A sample run of the program is displayed below: Press any key to continue " , - You may find it useful to use input/output redirection while testing your program so that you can have large input files. Recall that from the command line you can use the command: my_program.exe will run the my_ number_generator.exe program and pipe all of the output from that program as input to the my_program.exe executable and then finally take the output from that program and redirect it to a file named output.txt.

Answers

To create a program that filters a list of non-negative integers, removing duplicates and sorting them from smallest to largest, follow these steps:

1. Initialize an empty set, which will be used to store unique integers.

```python
unique_integers = set()
```

2. Read integer values from standard input until -1 is entered. For each integer, check if it's non-negative and not already in the set. If it meets these conditions, add it to the set.

```python
while True:
   integer = int(input())
   if integer == -1:
       break
   if integer >= 0:
       unique_integers.add(integer)
```

3. Sort the unique integers and print them one by one.

```python
for number in sorted(unique_integers):
   print(number)
```

Here's the complete program in python:

```python
unique_integers = set()

while True:
   integer = int(input())
   if integer == -1:
       break
   if integer >= 0:
       unique_integers.add(integer)

for number in sorted(unique_integers):
   print(number)
```

Now you have a program that filters a list of non-negative integers, removes duplicates, and sorts them in ascending order. To use input/output redirection while testing, run the program with the following command:

```
my_number_generator.exe | python my_program.py > output.txt

Which file is the boot loader in Windows 7/Vista?A. Winload.exeB. BCDC. Setup.exeD. Ntoskrnl.exe

Answers

In Windows 7/Vista, the boot loader is Winload.exe. A

The file plays a crucial role in the boot process by loading the operating system's kernel and its required drivers.
Here is a brief step-by-step explanation of the boot process in Windows 7/Vista:
When you power on your computer, the BIOS initializes the hardware and searches for a bootable device.
Upon finding a bootable device, the BIOS loads the Master Boot Record (MBR) from the device into memory.
The MBR contains the partition table and a small program called the boot sector code.

This code identifies the active partition and loads its boot sector into memory.

The boot sector contains another small program called the boot manager (in Windows 7/Vista, this is the Windows Boot Manager).

This program reads the Boot Configuration Data (BCD) file to identify the location of the operating system's boot loader.
The Windows Boot Manager then loads Winload.exe (the boot loader) from the System Reserved partition or the primary system partition.
Winload.exe locates and loads the operating system's kernel (Ntoskrnl.exe) and its required drivers into memory.
Once the kernel and drivers are loaded, the operating system starts, and you see the Windows login screen.

It is both a file-based storage and a block-based storage.

Answers

The correct statement about the AWS S3 is that it is an object-based storage. However, it is important to note that S3 also supports both file-based storage and block-based storage through additional features such as Amazon EFS and Amazon EBS. So, option (C) is correct.

Explanation:

The correct statement about the AWS S3 is that it is an object-based storage. S3 stands for Simple Storage Service and it is a highly scalable and durable storage service provided by Amazon Web Services (AWS). S3 is designed to store and retrieve any amount of data from anywhere on the web, and it stores data as objects rather than blocks or files. Objects in S3 consist of data, metadata, and a unique identifier, and they can be up to 5 terabytes in size.

For option A: "It is a file-based storage," is incorrect because S3 is not a file-based storage. While it is possible to store files in S3, they are stored as objects, not as files.

For Option B: "It is a block-based storage," is also incorrect. S3 is not a block-based storage, as it does not use block-level storage. Block-based storage systems divide data into small blocks that are managed individually, while S3 stores data as objects.

For Option D: "It is both a file-based storage and a block-based storage," is also incorrect. As mentioned earlier, S3 is not a file-based or block-based storage system. It is an object-based storage system that is designed to store and retrieve data as objects.

To make SQL code more readable and maintainable, most SQL programmers use one line per column definition, also known as attribute definition.

SQL, or Structured Query Language, is a programming language used to manage and manipulate relational databases. When writing SQL code to define a table, programmers typically define each column, or attribute, separately. This process involves specifying the name of the column, the data type it will store, and any additional constraints or requirements.

By using one line per column definition, programmers can improve the readability of their SQL code by making it easier to understand and follow. This format also makes it easier to identify errors or issues with the code, as each column is defined on its line and can be easily reviewed and verified.

In addition to improving readability, using one line per column definition can also make SQL code easier to maintain over time. As changes are made to the database structure or new tables are added, the ability to quickly review and update column definitions can help ensure the accuracy and integrity of the data stored in the database.

True or False: Block elements are normally displayed without starting a new line.

Answers

False. Block elements are normally displayed as a separate block and start on a new line.

False. Block-level elements are normally displayed on a new line, and they take up the full width available to them by default. By definition, block-level elements are those that create a block of content and take up the entire width of their parent container. Examples of block-level elements include headings (<h1> to <h6>), paragraphs (<p>), lists (<ul>, <ol>, and <li>), divs (<div>), and sections (<section>). When these block-level elements are rendered in a web page, they are typically displayed on a new line and take up the full width available to them. This is in contrast to inline elements like <span> or <a>, which are displayed inline with the surrounding content and do not create a new line.

Answers

The controller that manages a stack of View Controllers indicating the history of screens the user has visited is called a Navigation Controller.

This type of controller is commonly used in iOS app development to enable users to navigate through different screens or views within an app. A Navigation Controller is designed to keep track of the user's navigation path, or history, within an app. When a user taps on a button or interacts with an element that triggers a new screen to appear, the Navigation Controller adds a new View Controller to the stack. The user can then navigate back through their history of screens by using the back button provided by the Navigation Controller.

The Navigation Controller can also be used to display a navigation bar at the top of each screen, providing users with context and a clear indication of their current location within the app. This bar typically includes buttons for returning to previous screens or accessing additional functionality. Overall, the Navigation Controller is a crucial component in many iOS apps, allowing developers to create intuitive and user-friendly navigation experiences that enable users to move seamlessly through an app's content.

(t/f) addi instruction's immediate number needs to be extended to 32bit before given to alu. o true o false

Answers

The given statement "ADDI instruction's immediate number needs to be extended to 32bit before given to ALU" is false because the immediate number in an ADDI instruction is typically a 16-bit signed integer, which is already the appropriate size for use by the ALU, so it does not need to be extended to 32-bit.

The immediate number of ADDI instructions in most computer architectures is typically a 16-bit signed integer. Therefore, it does not need to be extended to 32-bit before being given to the ALU. The ALU can directly perform the arithmetic operation using the 16-bit immediate and the contents of the specified register(s). However, some architectures may use a different size for the immediate, in which case the answer may be different.

Given the char * variables name1, name2, and name3, write a fragment of code that assigns the largest value to the variable max (assume all three have already been declared and have been assigned values). You should be assigning the string pointers (rather than copying the contents).if ((strcmp(name1,name2)>0)&&(strcmp(name1,name3)>0)){max=name1;}else if ((strcmp(name2,name1)>0)&&(strcmp(name2,name3)>0)){max=name2;}else if((strcmp(name3,name1)>0)&&(strcmp(name3,name2)>0)){max=name3;}else if(strcmp(name3,name1)==0){max=name1,name3;}else if (strcmp(name2,name1)==0){max=name2,name1;}else if (strcmp(name2,name3)==0){max=name2,name3;}else{max=name1,name2,name3;}

Answers

The provided code fragment effectively assigns the largest value among the char * variables name1, name2, and name3 to the variable max. If there is no single largest value, max is set to NULL.

Here is a refined version of your code to find the largest value among the three char * variables and assign it to the variable max:
c
if (strcmp(name1, name2) > 0 && strcmp(name1, name3) > 0) {
   max = name1;
} else if (strcmp(name2, name1) > 0 && strcmp(name2, name3) > 0) {
   max = name2;
} else if (strcmp(name3, name1) > 0 && strcmp(name3, name2) > 0) {
   max = name3;
} else {
   max = NULL;
}


This code compares the three char * variables, name1, name2, and name3, using the strcmp function. The strcmp function returns a value greater than 0 if the first string is lexicographically larger, 0 if they are equal, and a value less than 0 if the first string is lexicographically smaller. The code compares the strings pairwise and assigns the largest string to the variable max. If there is no single largest value (i.e., at least two of them are equal), max is set to NULL.

The provided code fragment effectively assigns the largest value among the char * variables name1, name2, and name3 to the variable max. If there is no single largest value, max is set to NULL. This solution uses the strcmp function to compare the strings and takes advantage of the fact that strcmp returns a value that indicates the lexicographic order of the strings being compared.

What is a dominant strategy?

A dominant strategy means that regardless of what the other player does, the player with the dominant strategy will always choose the same strategy. This results in the dominant strategy being the Nash equilibrium of the game, as both players will choose their dominant strategies. Additionally, the dominant strategy will always yield a higher payoff than any other strategy the player could choose.

1. They will always have an incentive to play that strategy regardless of what the other players do.
2. The Nash equilibrium of the game must specify the player playing their dominant strategy.
3. The dominant strategy will always yield that player a higher payoff than any of the other strategies they could play, regardless of what the other players do.

So, the correct answer is "all of the above." A dominant strategy is one that provides the best outcome for a player, no matter the strategies are chosen by the other players, and it plays a crucial role in finding the Nash equilibrium of a game.
