The given exercise involves creating a program in C++ that generates fortune cookie sayings based on the day of the week. Here's an explanation of the steps involved:

Create a new text file named "ex5_1.cpp" and add the required comments including your full name.

Include the necessary headers, such as <iostream> and <ctime>, and use the std namespace for convenience.

Implement the main() function.

Use the time() function to get the current time and store it in the variable tt.

Declare a pointer to a tm struct named dt and assign it the value returned by localtime(&t).

Declare an integer variable w and assign it the value of dt->tm_wday, which represents the day of the week (0-6, where 0 is Sunday).

Create a struct named "node" with three components: an int variable named index, a string variable named saying, and a pointer named next of type node.

Implement the addnode() function that takes an int and a string as parameters, creates an instance of the node struct, sets its index and saying values, and updates the next pointer to point to the tail node.

Implement the findSaying0() function that takes an int parameter, searches for a matching index in the linked list, and displays the associated saying.

In the main() function, call addnode() multiple times to build a singly linked list with index-saying pairs.

Finally, call findSaying0(w) in the main() function, passing the value of w (day of the week) to obtain the corresponding fortune cookie saying.

To capture the program's output, you can run it in a console or terminal and redirect the output to a text file using the command line.

The command in Linux that is used for conditional execution is the "if" command.

The "if" command allows you to perform different actions based on the outcome of a condition. It is commonly used in shell scripting to make decisions and control the flow of the program. To use the "if" command, you first specify the condition you want to check. This can be any valid expression that evaluates to either true or false. For example, you can check if a file exists, if a variable has a certain value, or if a command succeeds or fails.

After specifying the condition, you use the "then" keyword to indicate the action to be performed if the condition is true. This can be a single command or a block of commands enclosed in curly braces. If the condition is false, the commands following the "then" block are skipped. The "if" command can also be extended with additional keywords like "elif" (short for "else if") and "else" to handle multiple conditions. This allows you to create more complex decision-making structures in your scripts.

To count the number of students with scores in each range, we can read the grades from the input file and accumulate the counts for each range. Finally, we output the score ranges along with the corresponding count of scores within each range.

In order to solve this problem, we need to follow these steps. First, we read the input file "lab2_input.txt" and extract the grades. The first number in the file represents the total number of grades, so we can ignore it. We can use the FileReader and BufferedReader classes to read the file line by line.

Next, we initialize eight variables to represent the count of scores within each range: count0_24, count25_49, count50_74, count75_99, count100_124, count125_149, count150_174, and count175_200. We set all these variables to zero initially.

Then, we iterate over each grade in the input and compare it against the score ranges. Depending on the value of the grade, we increment the corresponding count variable. For example, if the grade is between 0 and 24, we increment count0_24 by 1. We continue this process for all the score ranges.

Finally, we output the score ranges along with the count of scores within each range. We can use the System.out.println() method to print the desired output format. For example, "[0 - 24]: 1" represents that there is 1 student with a score in the range of 0-24. We print the counts for all the ranges in a similar manner.

Normality is a fundamental assumption when it comes to statistical tests such as t-test, correlation, and regression. This means that data should follow a normal distribution. In this context, a normal distribution implies that data follow a bell-shaped curve.

When data follow this distribution, the mean, median, and mode are equal and lie in the middle of the curve.

How to check normality of data1.

Quantile-Quantile (Q-Q) PlotA Q-Q plot is used to graphically evaluate if the sample comes from a known distribution, such as the normal distribution. A 45-degree straight line is drawn in the graph to represent the normal distribution. The closer the points are to this line, the more normal the data.

If the plot is S-shaped, then it is right-skewed. If it has an inverted S-shape, it is left-skewed.2.

Kolmogorov-Smirnov Test

This test determines whether the sample's distribution is significantly different from a normal distribution. In this test, the null hypothesis assumes that the sample is normally distributed.

If the p-value is greater than 0.05, the null hypothesis is accepted, which means that the sample is normally distributed.3. Shapiro-Wilk Test

This test is also used to check normality.

It tests whether a random sample comes from a normally distributed population. The null hypothesis is that the population is normally distributed.

If the p-value is greater than 0.05, the null hypothesis is accepted, which means that the sample is normally distributed.

Based on the accumulated data of Cannie Group, we will use a Q-Q plot to check the normality of the data. Here is the Q-Q plot:student submitted image

The Q-Q plot indicates that the data is normal since the points are closer to the 45-degree straight line. Therefore, we can proceed with other statistical tests that assume normality, such as t-test and regression.

The data present in the file ranking. mat is of size 200x1, and it is of class double. Moreover, some values present in the data are 1, 15, 3, 5 8, 9, 14, 13, 12, 11, and 100....The Huffman encoding function can be written in Matlab using the following code snippet:```
function y = Huffman_Encoding_Function(x)
dict = huffmandict(x);
y = huffmanenco(x, dict);
end
```The above code defines a function with the name Huffman_Encoding_Function, which takes the input data x and returns the output y. The function first creates a dictionary for Huffman encoding using the function huffmandict. After that, the created dictionary is used to perform Huffman encoding on the input data using the function huffmanenco. Finally, the encoded output is returned by the function.

The given problem requires the creation of a Huffman encoding function using the Matlab software.

The code must be capable of encoding the data present in the loaded ranking.mat file. The file is of size 200x1 and is of class double. Moreover, the file contains some values such as 1, 15, 3, 5 8, 9, 14, 13, 12, 11, 100... which need to be encoded using Huffman encoding. In order to create the required function, two Matlab functions can be used: huffmandict and huffmanenco. The function huffmandict is used to generate a dictionary for Huffman encoding. Whereas, the huffmanenco function is used to perform Huffman encoding on the given data using the dictionary created by huffmandict. The resulting encoded output is returned by the function to the user.

Now let's look at the code snippet given above in detail. The code's first line defines the function's name to be created. Here, the function name is Huffman_Encoding_Function. The input data is passed to the function in the form of an array x. The output is also returned by the function in the form of an array y.In the next line, a dictionary for Huffman encoding is created using the function huffmandict. The function takes input data x as a parameter and returns a dictionary for Huffman encoding. The dictionary generated is assigned to a variable named dict.

Finally, the huffmanenco function is used to perform Huffman encoding on the input data using the dictionary created by huffmandict. The encoded output is then assigned to the variable y, which the function returns to the user. This is how a Huffman encoding function can be created using Matlab software. The function can be called multiple times to encode different datasets using the same dictionary. This approach can lead to efficient data compression, especially in cases where the input data contains redundant or repetitive information.

Thus, it can be concluded that a Huffman encoding function can be created using the Matlab software to encode the data present in the loaded ranking.mat file. The code for the function must include two Matlab functions: huffmandict and huffmanenco. The huffmandict function is used to create a dictionary for Huffman encoding, whereas the huffmanenco function is used to encode the data using the created dictionary. This approach can lead to efficient data compression, especially in cases where the input data contains redundant or repetitive information.

To create a set from an existing collection object, such as a list, you can use the `set()` constructor. Here's an example:

```

numbers_list = [2, 5, 19, 458, 6345, 8877]

set_numbers = set(numbers_list)

print("Converting list into set:", set_numbers)

```

Output:

```

Converting list into set: {2, 5, 19, 458, 6345, 8877}

```

As you can see, the `set()` constructor takes the list `numbers_list` and converts it into a set called `set_numbers`. The output shows the elements of the set in curly braces.

Similarly, to create a tuple from an existing collection object, such as a list, you can use the `tuple()` constructor. Here's an example:

```

numbers_list = [561, 1345, 1729, 2465]

tuple_numbers = tuple(numbers_list)

print("Converting list into tuple:", tuple_numbers)

```

Output:

```

Converting list into tuple: (561, 1345, 1729, 2465)

```

The `tuple()` constructor takes the list `numbers_list` and converts it into a tuple called `tuple_numbers`. The output shows the elements of the tuple enclosed in parentheses.

Lastly, to create a tuple using the "packing" technique, you can define a tuple with multiple elements separated by commas. Here's an example:

```

car_tuple = ("Tesla", "Mercedes-Benz", "Jeep")

print("Tuple with cars:", car_tuple)

```

Output:

```

Tuple with cars: ("Tesla", "Mercedes-Benz", "Jeep")

```

In this example, the tuple `car_tuple` is created with the elements "Tesla", "Mercedes-Benz", and "Jeep". The output shows the elements enclosed in parentheses.

To unpack the tuple and print its elements separately, you can use multiple variables to capture each element of the tuple. Here's an example:

```

car_tuple = ("Tesla", "Mercedes-Benz", "Jeep")

car1, car2, car3 = car_tuple

print("Unpacked tuple:")

print("Car 1:", car1)

print("Car 2:", car2)

print("Car 3:", car3)

```

Output:

```

Unpacked tuple:

Car 1: Tesla

Car 2: Mercedes-Benz

Car 3: Jeep

```

In this example, the tuple `car_tuple` is unpacked into three variables: `car1`, `car2`, and `car3`. Each variable captures one element of the tuple, which is then printed separately.

Based on Rectangle transposition, decrypt the following cipher text. (2 Points)Rectangle Transposition Cipher Rectangle Transposition Cipher is one of the classical ciphers.

The encryption technique is a simple transposition cipher that modifies the order of the plaintext's character. The method replaces the text's characters in accordance with a typical path through a rectangular table according to the secret key. The decryption process reverses the encryption process to retrieve the initial plaintext. It's also known as the Route Cipher.

Transposition is the name for a method of encryption in which plaintext is moved around or scrambled. A Route Cipher is a kind of transposition cipher that involves writing the plaintext in a grid of specific dimensions and then rearranging the letters to create the cipher. :The encrypted text is ".Let's decrypt the cipher using Rectangle Transposition.

The given for question is as follows:To find the number of ways that the passwords can be arranged, we need to find the number of permutations of the given string.

Let the length of the password be 4. Then,

Number of permutations = (number of ways to select the first character)(number of ways to select the second character)(number of ways to select the third character)(number of ways to select the fourth character)

= 36 × 36 × 36 × 36= (6 × 6)^4

= 6^8

= 1679616 (ii)

To determine the probability that at random, the passwords contain: (A) repeated symbols. We will find the number of passwords that do not contain any repeated symbols and divide it by the total number of possible passwords. We can select the four characters without repetition in (36 × 35 × 34 × 33) ways. So, the number of passwords that do not contain any repeated symbols is 36 × 35 × 34 × 33. The probability that the passwords contain no repeated symbols.

The `ping` command uses the echo message and `traceroute` uses the TTL message to measure performance through network. Ping is a networking utility tool that is used to measure the time it takes for data to travel from a source device to a destination device via the internet.

The time it takes for the request message to travel to the destination device and for the reply message to travel back to the source device is called the ping time. Traceroute is a networking utility tool that is used to trace the path that data takes from a source device to a destination device via the internet. It works by sending a series of ICMP echo request messages to the destination device, with each message having an incrementally increasing Time to Live (TTL) value.

The TTL value is a network hop counter that determines how many network devices the message can pass through before it is dropped. When the message reaches a network device with a TTL value of zero, the device sends back an ICMP error message to the source device, which indicates that the message was dropped. The traceroute utility tool is commonly used to diagnose network routing issues.
