{
/* Period and duty in microseconds */
uint16_t pwmPeriod = 3000;
uint16_t duty = 0;
uint16_t dutyInc = 100;
/* Sleep time in microseconds */
uint32_t time = 50000;
PWM_Handle pwm1 = NULL;
PWM_Handle pwm2 = NULL;
PWM_Params params;
LED_Handle ledGreen = NULL;
LED_Handle ledYellow = NULL;
/* Call driver init functions. */
PWM_init();
PWM_Params_init(¶ms);
params.dutyUnits = PWM_DUTY_US;
params.dutyValue = 0;
params.periodUnits = PWM_PERIOD_US;
params.periodValue = pwmPeriod;
pwm1 = PWM_open(CONFIG_PWM_0, ¶ms);
if (pwm1 == NULL) {
/* CONFIG_PWM_0 did not open */
while (1);
}
PWM_start(pwm1);
pwm2 = PWM_open(CONFIG_PWM_1, ¶ms);
if (pwm2 == NULL) {
/* CONFIG_PWM_1 did not open */
while (1);
}
PWM_start(pwm2);
ledGreen = LED_open(CONFIG_LED_0);
ledYellow = LED_open(CONFIG_LED_1);
/* Loop forever incrementing the PWM duty */
while (1) {
LED_control(ledGreen, LED_STATE_ON);
LED_control(ledYellow, LED_STATE_OFF);
duty = (duty + dutyInc);
if (duty == pwmPeriod || (!duty)) {
dutyInc = -dutyInc;
}
usleep(1000);
LED_control(ledGreen, LED_STATE_OFF);
LED_control(ledYellow, LED_STATE_ON);
}
}
So, with these changes, the code will make the green and yellow lights on the launchpad blink.

The Methods For each of the following, create a static method with the appropriate inputs and outputs. Call each of them in the main method. 2.1 Uniqueness Write a method called unique() which takes in a List and returns true if all the items in the List are unique. All the items are unique if none of them are the same. 2
Return false otherwise. 2.2 All Multiples Write a method named allMultiples () which takes in a List of integers and an int. The method returns a new List of integers which contains all of the numbers from the input list which are multiples of the given int. For example, if the List is [1,25,2,5,30,19,57,2,25] and 5 was provided, the new list should contain [25,5,30,25]. 2.3 All Strings of Size Write a method named allStringsOfSize() which takes in a List and an int length. The method returns a new List which contains all the Strings from the original list that are length characters long. For example, if the inputs are ["I", "like", "to", "eat", "eat", "eat", "apples", "and", "bananas"] and 3, the new list is ["eat", "eat", "eat", "and"]. 2.4 String To List of Words Write a method called stringToList0fWords() which takes in a String converts it into a list of words. We assumes that each word in the input string is separated by whitespace. 3
If our input String is "Hello, world! ", then the output should be ["Hello, ", "world!"]. For extra credit, sanitize the String, cleaning it up so that we remove the punctuation and other extraneous characters such that the output in the above example would become ["Hello", "world"] This method returns List⟩.
Here are the java methods for each problem statement. The main method calls all these methods. Let us start with the first one:
1. Uniqueness Write a method named `unique` which accepts a List of type T and returns true if all the items in the list are unique. Otherwise, return false.
public static boolean unique(List list) {
return new HashSet<>(list).size() == list.size();
}
2. All MultiplesWrite a method named `allMultiples` which accepts two parameters; a List of integers and an int. The method returns a new List of integers containing all the numbers from the input list which are multiples of the given int.
public static List allMultiples(List list, int num) {
return list.stream()
.filter(i -> i % num == 0)
.collect(Collectors.toList());
}
3. All Strings of SizeWrite a method named `allStringsOfSize` which accepts two parameters; a List of Strings and an int length. The method returns a new List of type String which contains all the Strings from the original list that are length characters long.```
public static List allStringsOfSize(List list, int length) {
return list.stream()
.filter(s -> s.length() == length)
.collect(Collectors.toList());
}
4. String To List of WordsWrite a method named `stringToListOfWords` which accepts a String and converts it into a list of words. We assume that each word in the input string is separated by whitespace.
public static List stringToListOfWords(String s) {
String[] words = s.split("\\W+");
return Arrays.asList(words);
}
After defining all these static methods, we can now call them in the `main` method to get the results for each of them.```public static void main(String[] args) {
// Testing unique method
List list1 = Arrays.asList("apple", "banana", "orange");
List list2 = Arrays.asList(1, 2, 3, 4, 5);
System.out.println(unique(list1)); // true
System.out.println(unique(list2)); // true
List list3 = Arrays.asList(1, 2, 3, 4, 5, 6, 1);
System.out.println(unique(list3)); // false
// Testing allMultiples method
List list4 = Arrays.asList(1, 25, 2, 5, 30, 19, 57, 2, 25);
List multiples = allMultiples(list4, 5);
System.out.println(multiples); // [25, 5, 30, 25]
// Testing allStringsOfSize method
List list5 = Arrays.asList("I", "like", "to", "eat", "eat", "eat", "apples", "and", "bananas");
List strings = allStringsOfSize(list5, 3);
System.out.println(strings); // [eat, eat, eat, and]
// Testing stringToListOfWords method
String s = "Hello, world!";
List words = stringToListOfWords(s);
System.out.println(words); // [Hello, world]
}
In conclusion, we have defined and implemented four static methods that solve four distinct problems. We have then called all these methods in the main method to get the desired results.

HELP HELP HELP.. THE OUTPUT FOR THIS CODE IS NOT WORKING IN MY PYTHON .. CAN ANYBODY GIVE ME A SCREENSHOT OF THE OUTPUT FROM PYTHON ITSELF NOT WRITING DOWN AS REGULAR TEXT
KNN cluster classification works by finding the distances between a query and all examples in its data. The specified number of examples (K) closest to the query are selected. The classifier then votes for the most frequent label found.
There are several advantages of KNN classification, one of them being simple implementation. Search space is robust as classes do not need to be linearly separable. It can also be updated online easily as new instances with known classes are presented.
A KNN model can be implemented using the following steps:
Load the data;
Initialise the value of k;
For getting the predicted class, iterate from 1 to total number of training data points;
Calculate the distance between test data and each row of training data;
Sort the calculated distances in ascending order based on distance values;
Get top k rows from the sorted array;
Get the most frequent class of these rows; and
Return the predicted class.
For your assignment, you will build a KNN classifier in Python.
The CSV file has data like this:
15,66,237,0,Strategy
21,60,238,0,Platformer
14,78,176,1,Strategy
10,67,216,1,Strategy
19,69,185,1,RPG
34,72,138,0,Platformer
13,49,208,1,Strategy
25,65,213,0,RPG
31,64,235,1,RPG
16,50,122,1,Platformer
32,70,232,0,Platforme
I can help you build a KNN classifier in Python using the provided steps and the CSV file. Let's start by loading the data from the CSV file. Assuming the file is named "data.csv," you can use the following code to load the data:
```python
import csv
def load_data(file_path):
with open(file_path, 'r') as file:
csv_reader = csv.reader(file)
data = list(csv_reader)
return data
data = load_data('data.csv')
```
Next, we can define a function to calculate the Euclidean distance between two data points. We'll use this function to compute the distances between the test data and each row of the training data. Here's the code for the distance calculation:
```python
import math
def euclidean_distance(point1, point2):
distance = 0
for i in range(len(point1) - 1):
distance += (float(point1[i]) - float(point2[i]))**2
return math.sqrt(distance)
```
Now, let's implement the KNN classifier function using the provided steps:
```python
def knn_classify(data, query, k):
distances = []
for row in data:
distance = euclidean_distance(row[:-1], query)
distances.append((distance, row[-1])) # Append a tuple of (distance, label)
distances.sort() # Sort the distances in ascending order
neighbors = distances[:k] # Get the top k rows with the smallest distances
class_votes = {}
for neighbor in neighbors:
label = neighbor[1]
if label in class_votes:
class_votes[label] += 1
else:
class_votes[label] = 1
# Find the label with the highest vote
predicted_class = max(class_votes, key=class_votes.get)
return predicted_class
```
With the KNN classifier implemented, you can now use it to classify new instances. Here's an example of how you can classify a test instance using the provided data:
```python
test_instance = [20, 70, 200, 0] # Sample test instance
k = 3 # Number of nearest neighbors to consider
predicted_label = knn_classify(data, test_instance, k)
print("Predicted label:", predicted_label)
```
Make sure to adjust the file path and modify the test instance and k value according to your requirements. That's it! You now have a KNN classifier implemented in Python using the provided steps and can use it to classify new instances.

The agile view of iterative customer communication and collaboration is applicable to all software engineering practice. Explain and give an example of application.
The Agile view of iterative customer communication and collaboration is applicable to all software engineering practices because the Agile approach recognizes that the customer's requirements and needs will likely change over time.
The approach values customer involvement throughout the development process, allowing for changes and iterations to be made in response to feedback and new information.In an Agile approach, customer collaboration is ongoing throughout the project. Customers are consulted at each stage of development, from planning to testing, and their feedback is used to inform subsequent iterations of the software. An example of an Agile approach to software development is Scrum. In Scrum, a cross-functional team works collaboratively to deliver working software in short iterations, known as sprints. At the beginning of each sprint, the team meets with the product owner, who represents the customer, to determine the top priorities for the next iteration.
The team then works together to develop and test the software, with frequent check-ins with the product owner to ensure that the product is meeting their needs. At the end of each sprint, the team presents their working software to the product owner, and any necessary changes are incorporated into the next sprint. This iterative process allows for frequent communication and collaboration with the customer, ensuring that the final product meets their needs.

Internet programing Class:
What are the two main benefits of DNS?
The two main benefits of DNS are efficient resource management and user-friendly addressing.
DNS, which stands for Domain Name System, serves as a crucial component of the internet infrastructure. It plays a vital role in translating human-readable domain names into IP addresses, enabling efficient resource management and user-friendly addressing.
Firstly, DNS ensures efficient resource management by maintaining a distributed database of domain names and their corresponding IP addresses. When a user enters a domain name in their web browser, the DNS system quickly looks up the IP address associated with that domain name.
This process reduces the burden on individual servers and allows for load balancing across multiple servers. By distributing the load, DNS helps to optimize the performance and reliability of internet services, ensuring that websites and other online resources are accessible to users without overwhelming individual servers.
Secondly, DNS facilitates user-friendly addressing by providing meaningful domain names that are easy to remember and type. Imagine if you had to remember the IP address of every website you wanted to visit, such as 192.0.2.1 for example.
This would be highly impractical and error-prone. Instead, DNS allows us to use domain names like www.example.com, which are more intuitive and memorable. It simplifies the process of accessing resources on the internet, making it easier for users to navigate the online world.
In summary, the two main benefits of DNS are efficient resource management through load balancing and user-friendly addressing via domain names. DNS optimizes the distribution of internet traffic and enables users to access online resources using intuitive and memorable domain names.

____________________ is a debugging technique that allows packets to explicitly state the route they will follow to their destination rather than follow normal routing rules.
The debugging technique you are referring to is called "source routing." It enables packets to specify the exact path they should follow to reach their destination, bypassing the usual routing rules.
Source routing is a debugging technique that grants packets the ability to determine their own routing path instead of relying on standard routing protocols. In traditional networking, routers determine the optimal path for packet delivery based on routing tables and protocols like OSPF or BGP. However, in scenarios where network issues or specific debugging needs arise, source routing can be employed to override these routing decisions.
With source routing, the sender of a packet can explicitly define the path it should follow through the network by specifying a series of intermediate destinations or router addresses. This information is encapsulated within the packet header, allowing it to traverse the network based on the specified route. This technique allows network administrators or developers to investigate and troubleshoot network connectivity or performance problems by forcing packets to traverse specific network segments or avoid problematic routes.
It's important to note that source routing can introduce security risks if not implemented carefully. Malicious actors could potentially exploit source routing to bypass security measures or launch attacks. As a result, source routing is typically disabled or restricted in production networks and used primarily for debugging and troubleshooting purposes in controlled environments.

Here's a Java program that prints numbers from 10 to 200, replacing numbers divisible by 3 with "Fizz," numbers divisible by 5 with "Buzz," and numbers divisible by both 3 and 5 with "FizzBuzz."
To achieve the desired output, we can use a for loop to iterate through the numbers from 10 to 200. Inside the loop, we can use conditional statements to check if the current number is divisible by 3, 5, or both. Based on the divisibility, we can print "Fizz," "Buzz," or "FizzBuzz" accordingly. For other numbers, we can simply print the number itself.
The program starts with a for loop that initializes a variable `i` to 10 and increments it by 1 in each iteration until it reaches 200. Inside the loop, we use conditional statements to check the divisibility of `i`. If it is divisible by both 3 and 5, we print "FizzBuzz." If it is divisible by 3, we print "Fizz." If it is divisible by 5, we print "Buzz." If none of these conditions are met, we simply print the value of `i`.
By executing this program, you will get the expected output as described in the question.

1. Suppose that an IP datagram of 1895 bytes (it does not matter where it came from) is trying to be sent into a link that has an MTU of 576 bytes. The ID number of the original datagram is 422. Assume 20-byte IP headers.
a. (2) How many fragments are generated of (for?) the original datagram?
b. (8) What are the values in the various fields in the IP datagram(s) generated that are related to fragmentation? You need only specify the fields that are affected (changed) by fragmentation, but you must supply such a set for EVERY fragment that is created.
this is computer network question and should be in a text document format
a. Four fragments will be generated for the original datagram.
b. The values in the various fields in the IP datagram(s) generated that are related to fragmentation are as follows:
Fragment 1: ID = 422; fragment offset = 0; MF = 1; Total Length = 576; Fragment Length = 556;Flag = 1Fragment 2: ID = 422; fragment offset = 91; MF = 1; Total Length = 576; Fragment Length = 556;Flag = 1Fragment 3: ID = 422; fragment offset = 182; MF = 1; Total Length = 576; Fragment Length = 556;Flag = 1Fragment 4: ID = 422; fragment offset = 273; MF = 0; Total Length = 263; Fragment Length = 243;Flag = 0EMaximum transmission unit (MTU) is the largest data chunk that can be transmitted over a network. In this case, an IP datagram of 1895 bytes is trying to be sent into a link that has an MTU of 576 bytes. This means that the datagram needs to be fragmented into smaller chunks before being sent across the network.
Each of these fragments will be a new IP datagram with a different IP header. The fragmentation process is carried out by the sender’s host IP software.
When fragmentation occurs, the original datagram is broken down into smaller pieces. Each piece is known as a fragment. The different fields affected by fragmentation are ID, fragment offset, MF (more fragments) flag, total length, and fragment length.

Define a function max (const std::vector & ) which returns the largest member of the input vector.
Here's a two-line implementation of the max function:
```cpp
#include <vector>
#include <algorithm>
int max(const std::vector<int>& nums) {
return *std::max_element(nums.begin(), nums.end());
}
```
The provided code defines a function called "max" that takes a constant reference to a vector of integers as input. This function is responsible for finding and returning the largest element from the input vector.
To achieve this, the code utilizes the `<algorithm>` library in C++. Specifically, it calls the `std::max_element` function, which returns an iterator pointing to the largest element in a given range. By passing `nums.begin()` and `nums.end()` as arguments to `std::max_element`, the function is able to determine the maximum element in the entire vector.
The asterisk (*) in front of `std::max_element(nums.begin(), nums.end())` dereferences the iterator, effectively obtaining the value of the largest element itself. This value is then returned as the result of the function.
In summary, the `max` function finds the maximum value within a vector of integers by utilizing the `std::max_element` function from the `<algorithm>` library. It is a concise and efficient implementation that allows for easy retrieval of the largest element in the input vector.
The `std::max_element` function is part of the C++ Standard Library's `<algorithm>` header. It is a versatile and powerful tool for finding the maximum (or minimum) element within a given range, such as an array or a container like a vector.
By passing the beginning and end iterators of the vector to `std::max_element`, it performs a linear scan and returns an iterator pointing to the largest element. The asterisk (*) is then used to dereference this iterator, allowing us to obtain the actual value.
This approach is efficient, as it only requires a single pass through the elements of the vector. It avoids the need for manual comparisons or loops, simplifying the code and making it less error-prone.
Using `std::max_element` provides a concise and readable solution for finding the maximum element in a vector. It is a recommended approach in C++ programming, offering both simplicity and efficiency.

A shell interpreter can be any of the Unix/Linux shells like bash, csh, zsh, and so on.A SCOPE folder is created to store the text files for this script. The SCOPE folder can be created in the current directory. If the folder does not exist, the script creates it. A filename variable is created to store the name of the text file. The variable is initialized to "SCOPE/$name.txt" to store the file in the SCOPE folder. The touch command is used to create an empty text file with the filename specified in the variable. The echo command is used to write the user's address to the text file.The cat command is used to display the file contents to the user. The user is then prompted to enter if they want to add an alternate address or not. If the user selects yes, then the script prompts the user to enter the alternate address. The echo command is used to write the alternate address to the text file. The cat command is used again to display the file contents to the user after the alternate address is appended to the file.If the user selects no, then the script terminates. The script can be modified to include error handling for invalid inputs. The script can also be modified to append multiple alternate addresses to the file if needed.

The user is then prompted to enter if they want to add an alternate address or not. If the user selects yes, then the script prompts the user to enter the alternate address, which is then appended to the file. If the user selects no, then the script terminates. The script can be modified to include error handling for invalid inputs and to append multiple alternate addresses to the file if needed.
