Write a function solution that returns an arbitrary integer which is greater than n.
Answer:
public static int greaterThanInt(int n){
return n+10;
}
Explanation:
This is a very simple method in Java. it will accept an argument which is an integer n and return n+10 since the question requires that an arbitrary integer greater than n be returned adding any int value to n will make it greater than n.
A complete java program calling the method is given below:
import java.util.Scanner;
public class ANot {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Please enter an integer");
int n = in.nextInt();
int greaterInt = greaterThanInt(n);
System.out.println("You entered "+n+", "+greaterInt+" is larger than it");
}
public static int greaterThanInt(int n){
return n+10;

Write pseudocode to represent the logic of a program that allows a user to enter three values then outputs the product of the three values. (If you're not sure of the definition of product be sure to look it up to verify its meaning.)
Final answer:
The pseudocode for a program that outputs the product of three user-entered values involves prompting the user for each value, calculating the product by multiplication, and displaying the result.
Explanation:
Writing Pseudocode for a Multiplication Program
The task is to write pseudocode that represents the logic of a program allowing a user to enter three values and then outputs the product of these values. The product refers to the result of multiplying the three numbers together. Below is the pseudocode for accomplishing this task:
START
Prompt user to enter the first value
Read firstValue
Prompt user to enter the second value
Read secondValue
Prompt user to enter the third value
Read thirdValue
Set product to firstValue multiplied by secondValue multiplied by thirdValue
Output product
END
This simple algorithm prompts the user to input three separate values and calculates the product by multiplying them together. The result is then displayed to the user.
Final answer:
The pseudocode for calculating the product of three user-entered values consists of reading the values, computing the product, and outputting the result.
Explanation:
The student is asking for pseudocode to calculate the product of three values entered by the user. Pseudocode is an informal way of programming description that does not require any strict programming language syntax, yet it describes the logic of the algorithm clearly. Below is an example of how this pseudocode might look:
START
Prompt user for first value
Read value1
Prompt user for second value
Read value2
Prompt user for third value
Read value3
Set product = value1 * value2 * value3
Output product
END
This pseudocode begins by prompting the user to enter three values. It then reads the values into three variables, calculates the product of these values by multiplying them, and finally outputs the product.

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string.
Answer:
import java.util.Scanner;
public class ANot {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Please enter a word");
String word = in.next();
System.out.println("Please enter a character");
char ca = in.next().charAt(0);
int countVariable = 0;
for(int i=0; i<word.length(); i++){
if(ca ==word.charAt(i))
countVariable++;
}
System.out.println(countVariable);
}
}
Explanation:
Using the Scanner Class prompt and receive the users input (the word and character). Save in seperate variablescreate a counter variable and initialize to 0Use a for loop to iterate over the entire length of the string.Using an if statement check if the character is equal to any character in string (Note that character casing upper or lower is not handled) and increase the count variable by 1print out the count variableIn a point-to-point single network, how many physical links will there be when a packet is transmitted?
Answer:
One
Explanation:
A network is the interconnection and communication of two or more computer devices. Computer systems on a network shares resources with one another, using network standards like OSI and TCP/IP suite model and using the protocols on each layers.
There are two major types of network communication between devices and they are peer to peer or point to point Network and client-server network.
Point to point Network uses one secure physical link to connect two computers or routers in a network.
in a multitasking system, the context-switch time is 1ms and the time slice is 10ms. Will the CPU efficiency increase or decrease when we increase the time slice to 15ms? Explain why.
Answer:
Answer explained below
Explanation:
It depends on the arrival time and burst time of the processes. On increasing the time slice the waiting and turn around time can increase and decrease both.
As waiting time and turn around time are the major criteria for calculating the efficiency, so we can't say whether the efficiency will increase or decrease.
Write a program that asks the user to enter three names, and then displays the names sorted in ascending order. For example, if the user entered "Charlie", "Leslie", and "Andy", the program would display: Andy
Answer:
Explanation:
//import the package
import java.util.Scanner;
import java.util.Arrays;
//create the arrays
private static String[] names = new String[3];
/we ask the 3 names
Scanner scan = new Scanner(System.in);
System.out.println("You must enter 3 names");
//a for cycle to get the names
for(int i=0;i<names.length;i++){
System.out.println("Enter name: ");
names[i]= scan.next();
}
// we print in order
scan.close();
Arrays.sort(names);
System.out.println("Sorted List "+Arrays.toString(names));
}
}
In Python, you could write a program to sort three entered names by creating an empty list, using a for loop to prompt the user to enter a name three times and add it to the list, sorting the list, and then using another for loop to print out the sorted names.
Explanation:The subject of this question is writing a program that can sort three entered names in ascending order. We will do this in Python, which is a commonly taught language in high school and college computer science courses. Let's take a look at how this could work:
names = []This program starts by creating an empty list, 'names'. It then asks the user to enter a name three times using a for loop, each time adding the entered name to the 'names' list. After all three names have been entered, it uses the .sort() method to sort the names in ascending order (alphabetically). Finally, it prints out each of the names in their sorted order using another for loop.

Explanation:
Consider a system that contains 32K bytes. Assume we are using byte addressing, that is assume that each byte will need to have its own address, and therefore we will need 32K different addresses. For convenience, all addresses will have the same number n , of bits, and n should be as small as possible. What is the value of n ?
Answer:
n = 15
Explanation:
Using
Given
Number of bytes = 32k
At the smallest scale in the computer, information is stored as bits and bytes.
In the cases when used to describe data storage bits/bytes are calculated as follows:
Number of bytes when n = 1 is 2¹ = 2 bytes
When n = 2, number of bytes = 2² = 4 bytes
n = 3, number of bytes = 2³ = 8 bytes
So, the general formula is
Number of bytes = 2^n
In this case
2^n = 32k
Note that 1k = 1024 bytes,
So, 32k = 32 * 1024 bytes
Thus, 2^n = 32 * 1024
2^n = 2^5 * 2^10
2^n = 2^15
n = 15.
Final answer:
To address 32K bytes uniquely using byte addressing, 15 bits are required which [tex]2^{15}[/tex] equals 32768, the number of bytes in 32K. This demonstrates a fundamental concept of how memory is addressed in computing.
Explanation:
Understanding the minimum number of bits required to represent a certain amount of memory is a fundamental concept in computer science. To represent 32K bytes where 'K' stands for kilo (1024) due to binary base, we need to calculate the minimum number of bits (n) to address each byte. Essentially, 32K bytes equals 32 * 1024 = 32768 bytes. The question is how many bits are required to uniquely address each of these bytes.
To find the value of n, we rely on the principle that each bit can represent 2 states. Therefore, [tex]2^{n}[/tex] should be equal to or greater than 32768. Calculating this, we see that [tex]2^{15}[/tex] = 32768 exactly, indicating that 15 bits are sufficient to address 32K bytes uniquely. Thus, n = 15.
This example highlights how binary representation and addressing work in computing, illustrating why understanding of binary and byte addressing is crucial in fields related to computers and technology.

C++ :Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. If the input is 3, the output is:a.headsb.tailsc.headsFor reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time, in which case every program run output would be different, which is what is desired but can't be auto-graded. Your program must define and call a function: string HeadsOrTails() that returns "heads" or "tails".
NOTE: A common student mistake is to call srand() before each call to rand(). But seeding should only be done once, at the start of the program, after which rand() can be called any number of times.
The program is an illustration of random module.
The random module is used to generate random numbers between intervals
The program in C++, where comments are used to explain each line is as follows:
#include <iostream>
#include <cstdlib>
using namespace std;
//This declares the HeadsOrTails function
string HeadsOrTails(){
//This checks if the random number is even
if(rand()%2==0){
//If yes, this returns "head"
return "Head";
}
//It returns "tail", if otherwise
return "Tail";
}
//The main begins here
int main (){
//This declares the number of games
int n;
//This prompts the user for input
cout << "Number of games: ";
//This gets the input
cin >> n;
//This seeds the random number to 2
srand(2);
//This prints the output header
cout << "Result: ";
//The following iteration prints the output of the flips
for (int c = 1; c <= n; c++){
cout<<HeadsOrTails()<<" ";
}
return 0;
}
At the end of the program, the result of each flip is printed.

Convert the value of the following binary numbers to hexadecimal notation. (Note: this question has 2 parts; you must answer each part correctly to receive full marks. Do not include spaces, commas or subscripts in your answer.)
a. 11012 =
b. 111011102 =
Answer:
Explanation: Where binary numbers are made up of 0s and 1s, numbers in hexadecimal (base 16) contains digits from 0 to 9 as well as letters from A to F. Any number gotten from applying the placeholders (8,4,2,1) that is above 9 is changed into letters. Thus: 10 = A; 11 = B; 12 = C; 13 = D; 14 = E & 15 = F
Solving the question, we split the binaries groups of fours while adding 0s from the left hand side of incomplete groups of four to make it up to four.
I would place the placeholders in brackets for example 1(8) should be read as "number of 8s is 1; 0(2) as " number of 2s is 0"
1. 1101 in base to to base 16 = 1(8) 1(4) 0(2) 1(1)
= 8 + 4 + 0 + 1 = 13 = D
Therefore, 1101 base 2 is D in hexadecimal
2. 11101110 = 1110 & 1110 {group of four}
1110 = 1(8) 1(4) 1(2) 0(1)
= 8 + 4 + 2 + 0 = 14 = E
Therefore, 11101110 base 2 = EE in hexadecimal
A 1 MB digital file needs to transmit a channel with bandwidth of 10 MHz and the SNR is 10 dB. What is the minimum amount of time required for the file to be completely transferred to the destination?
Answer:
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.
Explanation:
We can calculate the channel capacity using Shannon's Capacity formula:
C = B + log₂ (1 + SNR)
Where C = Channel Capacity
B = Bandwidth of the Channel
SNR = Signal to Noise Ratio
We are given SNR in dB so we need to convert it into a ratio.
[tex]SNR_{dB}[/tex] = 10log₁₀ (SNR)
10 = 10log₁₀ (SNR)
1 = log₁₀ (SNR)
SNR = 10¹
SNR = 10
So, using Shannon Channel Capacity formula:
C = 10 x 10⁶ log₂ (1 + 10)
C = 34.5 MHz
Total amount of time required to transmit a 1MB file:
1MB = 1 x 8 Mbytes = 8Mb
C = 34.5 MHz = 34.5 Mb/s
Time required = 8Mb/34.5Mb/s = 0.23 seconds
A 1 MB digital file needs 0.23 seconds to transfer over a channel with bandwidth 10 MHz and SNR 10 dB.

To implement the function calcWordFrequencies that reads a list of words separated by spaces and outputs their frequencies, you can use a programming language like JavaScript. The function will prompt the user for input, then split the input string by spaces to get an array of words. After that, the function will count the occurrences of each word using an object to store the frequencies, and finally, it will log the words and their respective frequencies to the console.
Here is an example of how this function might look:
function calcWordFrequencies() {
var input = prompt('Enter a list of words separated by spaces:');
var words = input.split(' ');
var frequencies = {};
for (var i = 0; i < words.length; i++) {
var word = words[i].toLowerCase();
frequencies[word] = (frequencies[word] || 0) + 1;
}
for (var word in frequencies) {
console.log(word + ' ' + frequencies[word]);
}
}
Note: The example above converts all words to lowercase to count 'Mark' and 'mark' as two occurrences of the same word. You can remove the toLowerCase call if you want to distinguish between capitalized and lowercase words.
Final answer:
To count word frequencies in Python, use the input() function to collect user input, split the input into words, use a dictionary to track frequencies, then iterate and print each word with its frequency.
Explanation:
To implement the function calcWordFrequencies that reads a list of words from the user and outputs the frequency of each word, you can follow these steps in Python:
Use the input() function to prompt the user to enter a list of words separated by spaces.Create an empty dictionary to keep track of word frequencies.Split the input string into words using the split() method.Iterate over the list of words and for each word: If the word is already in the dictionary, increment its frequency.If the word is not in the dictionary, add it with a frequency of 1.Iterate over the dictionary and print each word along with its frequency.Here is an example code snippet that demonstrates these steps:
def calcWordFrequencies():If you hear that an airplane crashes into the Empire State Building, and you immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to what type of memory? a repressed memory a suppressed memory a flashbulb memory a pseudo-memory
Final answer:
If you think of the 9/11 terrorist attack when hearing about an airplane crashing into the Empire State Building, you are reacting to a flashbulb memory.
Explanation:
If you hear that an airplane crashed into the Empire State Building and immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to a memory known as flashbulb memory. A flashbulb memory is an exceptionally clear recollection of an important and emotionally charged event.
Thus, a flashbulb memory is a vivid, detailed, and long-lasting recollection of the circumstances surrounding a significant, emotionally charged event. Many people remember exactly where they were and how they heard about significant events like 9/11, even years later. These memories can be vivid and distinct, often accompanied by strong emotions.
The type of memory you are experiencing is called a flashbulb memory so the correct option is C. a flashbulb memory.
If you hear that an airplane crashes into the Empire State Building and immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to a flashbulb memory. It is a vivid and emotional memory of an unusual event that people believe they remember well. This memory is related to the strong emotional impact of the event, such as the 9/11 terrorist attack.A flashbulb memory is an exceptionally clear and vivid memory of an important and emotional event that people often believe they remember very well.For example, many people can recall exactly where they were and what they were doing when they first heard about the 9/11 attacks. These types of memories are characterized by their strong emotional associations and are typically remembered in great detail, though they are not immune to inaccuracies over time.Complete question:
If you hear that an airplane crashes into the Empire State Building, and you immediately think of the 9/11 terrorist attack on the World Trade Center, you are reacting to what type of memory?
A. a repressed memory
B. a suppressed memory
C. a flashbulb memory
D. a pseudo-memory
Delete Prussia from country_capital. Sample output with input: 'Spain:Madrid,Togo:Lome,Prussia: Konigsberg' Prussia deleted? Yes. Spain deleted? No. Togo deleted? No.
Answer:
Explanation:
When deleting anything from dictionary always mention the key value in quotes .
Ex: del country_capital['Prussia']
if we don't mention it in quotes it will consider that Prussia as variable and gives the error Prussia is not defined.
Code:
user_input=input("") #taking input from user
entries=user_input.split(',')
country_capital=dict(pair.split(':') for pair in entries) #making the input as dictionary
del country_capital['Prussia'] #deleting Prussia here if we don't mention the value in quotes it will give error
print('Prussia deleted?', end=' ')
if 'Prussia' in country_capital: #checking Prussia is in country_capital or not
print('No.')
else:
print('Yes.')
print ('Spain deleted?', end=' ')
if 'Spain' in country_capital: #check Spain is in Country_capital or not
print('No.')
else:
print('Yes.')
print ('Togo deleted?', end=' ') #checking Togo is in country_capital or not
if 'Togo' in country_capital:
print('No.')
else:
print('Yes.')
Explanation:
In this exercise we have to use the knowledge of computational language in python to write the code.
This code can be found in the attached image.
How can we described this code?user_input=input("")
entries=user_input.split(',')
country_capital=dict(pair.split(':') for pair in entries)
del country_capital['Prussia']
print('Prussia deleted?', end=' ')
if 'Prussia' in country_capital:
print('No.')
else:
print('Yes.')
print ('Spain deleted?', end=' ')
if 'Spain' in country_capital:
print('No.')
else:
print('Yes.')
print ('Togo deleted?', end=' ')
if 'Togo' in country_capital:
print('No.')
else:
print('Yes.')

How does a MIPS Assembly procedure return to the caller? (you only need to write a single .text instruction).
Answer:
A MIPS Assembly procedure return to the caller by having the caller pass an output pointer (to an already-allocated array).
