Answer: import java.util.Scanner;
public class ContactList {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// Read the number of word pairs in the list
int n = scnr.nextInt();
scnr.nextLine(); // Consume the newline character
// Read the word pairs and store them in two arrays
String[] names = new String[n];
String[] phoneNumbers = new String[n];
for (int i = 0; i < n; i++) {
String[] parts = scnr.nextLine().split(",");
names[i] = parts[0];
phoneNumbers[i] = parts[1];
}
// Read the name to look up
String name = scnr.nextLine();
// Call the getPhoneNumber method to look up the phone number
String phoneNumber = getPhoneNumber(names, phoneNumbers, name, n);
// Print the phone number, or "None" if the name is not found
if (phoneNumber != null) {
System.out.println(phoneNumber);
} else {
System.out.println("None");
}
}
public static String getPhoneNumber(String[] nameArr, String[] phoneNumberArr, String contactName, int arraySize) {
// Search for the name in the array and return the corresponding phone number
for (int i = 0; i < arraySize; i++) {
if (nameArr[i].equals(contactName)) {
return phoneNumberArr[i];
}
}
// If the name is not found, return null
return null;
}
}
Explanation: The program inputs the number of word sets, stores them in two clusters (names and phoneNumbers), and looks up a title by calling the getPhoneNumber strategy to return the comparing phone number. Prints phone number or "None" in the event that title not found. getPhoneNumber strategy takes nameArr, phoneNumberArr, contactName, and arraySize as contentions. The strategy looks for a title and returns the phone number in case found, something else invalid.
How can you optimize the performance of a function written in assembly language, while ensuring that it still performs the intended functionality and produces correct outputs? What factors should you consider when making trade-offs between speed and correctness?
While optimizing the performance of an assembly language function, a range of techniques can be implemented such as minimizing data access, reducing instruction count and utilizing hardware features like caching and pipelining.
Why is this so ?It is vital to validate that these optimizations do not compromise the intended functionality of the program or lead to erroneous results.
To achieve this, comprehensive testing should be deployed on different inputs and conditions to guarantee that the optimized function behaves as anticipated.
As one makes trade-offs between speed and correctness, various factors must be considered like the complexity of code, criticality of function and how error impacts system operation.

Write a program that allows the user to input two numbers and then outputs the average of the
numbers.
Answer:
Here's a Python program that takes two numbers as input from the user, calculates their average and displays it as output:
# Taking input from user
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
# Calculating average
average = (num1 + num2) / 2
# Displaying output
print("The average of", num1, "and", num2, "is", average)
Explanation:
In this program, we use the input() function to take input from the user in the form of two floating-point numbers. We then calculate their average by adding the two numbers and dividing the result by 2. Finally, we display the average to the user using the print() function.
Note: We convert the input to float data type using the float() function to ensure that the division operation produces a floating-point result even if the inputs are integers.

Some students are taking one class, some are taking both the classes. Write a function (getResult) with the list parameters (classOne and classTwo). The function will return the the list of students who are taking both classes. (PYTHON)
Sure, here's an example Python function that takes two lists of student names as arguments and returns a list of students who are taking both classes:
def getResult(classOne, classTwo):
# use set intersection to find students who are in both classes
studentsTakingBoth = list(set(classOne) & set(classTwo))
return studentsTakingBoth
Here's an example usage of the function:
classOne = ['Alice', 'Bob', 'Charlie', 'David']
classTwo = ['Bob', 'David', 'Eve', 'Frank']
studentsTakingBoth = getResult(classOne, classTwo)
print(studentsTakingBoth) # should print ['Bob', 'David']
In this example, the getResult function takes two lists classOne and classTwo as arguments, and finds the intersection of the two sets of students using the set intersection operator &. The resulting list is then returned. Note that we first convert the set intersection result into a list before returning it, since the set data type does not preserve the order of elements.

c. Explain how computer memory is measured a. Using a table, categorize bardware devices into input, output and storage devices b. State four similarities and four differences between first and second generation of computers e Describe the fourth and fifth generation of conten
Answer:
a. Computer memory is measured in bytes - a unit of digital information storage. Usually, computer memory is referred to as Random Access Memory (RAM), and its size is usually measured in gigabytes (GB). b. Input devices are used to input data into the computer system, for example, keyboard, mouse, scanner, and microphone. Output devices display and present data to the user, for example, monitor, printer, and speakers. Storage devices are used for storing data, for example, hard disk drive, solid-state drive, and USB drive. First-generation computers were large, bulky, and expensive, using vacuum tubes as their main components to process data. They were not user-friendly and lacked programming languages. Second-generation computers were faster, smaller, and cheaper than their predecessors. They used transistors in place of vacuum tubes, which reduced power consumption and generated less heat. They also used programming languages like COBOL and FORTRAN.
c. Fourth-generation computers were smaller in size and used microprocessors for processing data. They were characterized by faster speed, increased storage capacity, and cost-effectiveness. Fourth-generation computers could also support multitasking and multi-user operations. Fifth-generation computers are currently being developed, aiming at creating machine intelligence based on natural language processing, AI algorithms, and advanced parallel processing. They are expected to be able to learn from experience and understand and interpret human speech and natural language.
Overall, the evolution of computers has led to an exponential increase in both computing power and accessibility to users, as well as the use of more efficient and compact hardware devices.

Due to the slower speed of hard drives compared to RAM, the CPU avoids direct access to programs and data stored on them.
What is the RAM about?RAM's faster speed is attributed to its random accessibility design, enabling the CPU to rapidly access any portion. Also, hard drives necessitate the physical movement for data retrieval, leading to significantly longer wait times.
The initiation of the computer triggers the allocation of frequently accessed software and information into the RAM, thus enhancing its performance speed. The Central Processing Unit proceeds to retrieve the necessary programs and data from the Random Access Memory, since this process is considerably quicker than retrieving them from the hard drive.
