Set the Number of Cards if Necessary
Write code that sets the value of the variable num_cards to seven if its current value is less than seven. Otherwise, don't change the value. Assume that nuncards already has an initial value.
Answers
Answer:
In Python:
(a) Concatenate strings:
joined = str1+" "+str2
(b) Two Letters in Word :
two_letters = word[4]+word[-3]
(c) Set Numbers in Card
if num_cards < 7:
num_cards = 7
Explanation:
The code segments were written in Python
All variables were assumed to have been initialized
Solving (a): Concatenate strings:
To do this, we make use of + operator.
So, the concatenation of str1 and str2 with space in between is
str1+" "+str2
When assigned to variable joined, it becomes
joined = str1+" "+str2
Solving (b): Two Letters in Word :
The character at the 5th position is represented with index 4 i.e. word[4]
To access a character from the end, we make use of - sign. So, the third character from the end is word[-3]
Concatenate them using + operator.
So, we have:
two_letters = word[4]+word[-3]
Solving (c): Set Numbers in Card
Here, we make use of the if condtion.
First, check if num_cards is less than 7(i.e. num_cards < 7)
If true, assign num_cards to 7
So, we have:
if num_cards < 7:
num_cards = 7

HTML, XML and SGML are the markup languages (hence the "ML" suffix on each of their acronyms).
PHP, ASP and Javascript are scripting languages.
A kind of markup language is HTML. It "marks up" or encapsulates data using HTML tags that specify the data and explain how it will be used on the webpage. Following that, the web browser examines the HTML, which instructs it as to what sections are headings, paragraphs, links, etc.
What are the different web development languages?OOP scripting is used in Java, whereas OOP programming is used in Java. JavaScript code can only be run on a browser, while Java applications can run on a virtual machine or browser.
While JavaScript code is completely in text, Java code must be compiled. They both need various plug-ins.
Therefore, The "ML" suffix on each acronym stands for markup languages, which are HTML, XML, and SGML respectively. Scripting languages include JavaScript, ASP, and PHP.

Summary: Given integer values for red, green, and blue, subtract the gray from each value.
Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray).
Given values for red, green, and blue, remove the gray part.
Ex: If the input is:
130
50
130
the output is:
80 0 80
Find the smallest value, and then subtract it from all three values, thus removing the gray.

Suppose a program contains 500 million instructions to execute on a processor running on 2.2 GHz. Half of the instructions takes 3 clock cycles to execute, where rest of the instructions take 10 clock cycle. What is the execution time of the program
Answers
Answer:
1.48 s
Explanation:
Number of instructions = 500 million = 500 * 10⁶
clock rate = 1 / 2.2 GHz = 1 / (2.2 * 10⁹ Hz) = 0.4545 * 10⁻⁹ s
We need to compute the clocks per instruction (CPI)
The CPI = summation of (value * frequency)
CPI = (50% * 3 clock cycles) + (50% * 10 clock cycles)
CPI = (0.5 * 3) + (0.5 * 10) = 1.5 + 5 = 6.5
Execution time = number of instructions * CPI * clock rate
Execution time = 500 * 10⁶ * 6.5 * 0.4545 * 10⁻⁹ =1.48 s

Find the average CPI for each program given that the processor has a clock cycle time of 1 ns.
Answers
Answer:
The answer is "1.25"
Explanation:
[tex]{CPU \ time}= {instructions \times CPI \times cycle\ time}[/tex]
[tex]\therefore\\\CPI= \frac{CPU \ time}{instructions \times cycle \ time} \\\\cycle \ time = 1 \\\\ns = 10^{-9} s \\[/tex]
Also for this context, it executes the time = CPU time. So, the compiler A, we has
[tex]CPI_{A}= \frac{CPU \ time_{A}} {instructions_{A} \times cycle \ time}= \frac{1.1 s}{10^{9} \times 10^{-9} s}= 1.1[/tex]
For compiler B, we have
[tex]CPI_{B}= \frac{CPU \ times_{B}} {instructions_{B} \times cycle \ time}[/tex]
[tex]= \frac{1.5\ s}{ 1.2 \times 10^{9} \times 10^{-9} \ s}\\\\= \frac{1.5}{ 1.2 }\\\\= 1.25[/tex]
The average CPI for each program given that the processor has a clock cycle time of 1 ns is : 1.1, 1.25.
Average CPI for each programCPI (Complier A)=CPU time/Instruction×Cycle time
Where:
Cycle time=1ns=10^-9s
Hence:
CPI (Complier A)=1.1s/10^9×10^-9s
CPI (Complier A)=1.1
CPI (Complier B)=CPU time/Instruction×Cycle time
CPI (Complier B)=1.5s/1.2×10^9×10^-9s
CPI (Complier B)=1.25

The Boolean Foundation hosted a raffle to raise money for charity and used a computer program to notify the participants about the results. Unfortunately, the program they used was not very robust and all 250 participants received an email telling them that they won... and that their name is Shauna.
Improve this program by writing a function called sendEmail to print a personalized email to stdout. The function should take three parameters:
The name of the recipient
The prize for the raffle
Whether or not the recipient won
Use the email template from the existing program.
#include
using namespace std;
int main() {
cout << "Dear Shauna," << endl;
cout << "You are the winner of our raffle for charity." << endl;
cout << "The prize was: a stuffed giraffe toy" << endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
return 0;

cout << "Dear "<<name<<", " << endl;
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
cout << "The prize was: "<<prize<< endl;
cout << "Thank you for giving to charity!" << endl;
cout << "Sincerely," << endl;
cout << "The Boolean Foundation" << endl;
}
Explanation:
This defines the function along the three parameters
void sendEmail(string name, string prize, string win_lose){
This prints the salutation with the person's name
cout << "Dear "<<name<<", " << endl;
This prints if the person won or lost
cout << "You are the "<<win_lose<<" of our raffle for charity." << endl;
This prints the prize, if any

Explanation:
*The code is in Java.
Create the Scanner object to be able to get input
Initialize the constant values using final keyword, BASE_RATE, RATE_PER_HOUR, RATE_PER_MILE
Declare the variables, hours, miles, totalFee
Ask the user to enter the hours and miles
Calculate the totalFee, add BASE_RATE, multiplication of hours and RATE_PER_HOUR, multiplication of miles and RATE_PER_MILE
Print the output as in required format
The program named MoveEstimator that prompts a user for and accepts estimates for the number of hours for a job and the number of miles involved in the move and displays the total moving fee is as follows:

Using the Sampling Theorem, what is the minimum sampling rate (number of samples per second) required to convert the sensor signal into a digital representation?
If each sample is now quantised into 2048 levels, what will be the resulting transmitted bitrate in kbps?
Give your answer in scientific notation to 1 decimal place.
Hint: you firstly need to determine the number of bits per sample that produces 2048 quantisation levels
Answers
Answer:
3.2*10^5
Explanation:
By Nyquist's theorem we must have 2*14.5kHz=29kHz so 29,000 samples per second. 2048=2^11 so we have 11 bits per sample. Finally we have 29000*11 bits per second (bps) =319000=3.2 * 10^5
In this exercise we want to know how many bits will be transmitted between the two intelligences, so we have that:
[tex]3.2*10^5 bits[/tex]
What is the Nyquist's theorem?According to the theorem, the reconstructed signal will be equivalent to the original signal, respecting the condition that the original signal does not contain frequencies above or above this limit. This condition is called the Nyquist Criterion, or sometimes the Rahab Condition.
in this way we have:
[tex]2*14.5kHz=29kHz \\2048=2^11 =11 bits \\ 29000*11 =319000=3.2 * 10^5[/tex]

Answers
Answer:
C. is responsible for memory and device management.

Explanation:
An operating system platform is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system (OS) is essentially an interface between the computer’s hardware and all the software applications (programs) running on it.
Some examples of an operating system are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Ubuntu, etc.
The two statements which are true about an operating system (OS) are;
I. It's responsible for memory and device management. The operating system (OS) ensures proper allocation of memory to processes and manages all the input/output devices that are connected to the computer.
II. It's responsible for system security. The operating system (OS) makes sure the data integrity of a computer system isn't compromised i.e determining whether or not a request is to be processed through an authentication process.
RAM memory is intended?
Answers
Answer:
RAM is a short abbreviation for Random Access Memory. It is the physical working memory used by your PC to temporarily store computer data. Your PC stores all open applications, files, and any other data into RAM for quick access. The more RAM you have installed, the more programs you can run at the same time.
Consider the following method, remDups, which is intended to remove duplicate consecutive elements from nums, an ArrayList of integers. For example, if nums contains {1, 2, 2, 3, 4, 3, 5, 5, 6}, then after executing remDups(nums), nums should contain {1, 2, 3, 4, 3, 5, 6}.
public static void remDups(ArrayList nums)
{
for (int j = 0; j < nums.size() - 1; j++)
{
if (nums.get(j).equals(nums.get(j + 1)))
{
nums.remove(j);
j++;
}
}
}
The code does not always work as intended. Which of the following lists can be passed to remDups to show that the method does NOT work as intended?
A. {1, 1, 2, 3, 3, 4, 5}
B. {1, 2, 2, 3, 3, 4, 5}
C. {1, 2, 2, 3, 4, 4, 5}
D. {1, 2, 2, 3, 4, 5, 5}
E. {1, 2, 3, 3, 4, 5, 5}
Answers
Answer:
B. {1, 2, 2, 3, 3, 4, 5}
Explanation:
Given
The above code segment
Required
Determine which list does not work
The list that didn't work is [tex]B.\ \{1, 2, 2, 3, 3, 4, 5\}[/tex]
Considering options (A) to (E), we notice that only list B has consecutive duplicate numbers i.e. 2,2 and 3,3
All other list do not have consecutive duplicate numbers
Option B can be represented as:
[tex]nums[0] = 1[/tex]
[tex]nums[1] = 2[/tex]
[tex]nums[2] = 2[/tex]
[tex]nums[3] = 3[/tex]
[tex]nums[4] = 3[/tex]
[tex]nums[5] = 4[/tex]
[tex]nums[6] = 5[/tex]
if (nums.get(j).equals(nums.get(j + 1)))
The above if condition checks for duplicate numbers.
In (B), when the elements at index 1 and 2 (i.e. 2 and 2) are compared, one of the 2's is removed and the Arraylist becomes:
[tex]nums[0] = 1[/tex]
[tex]nums[1] = 2[/tex]
[tex]nums[2] = 3[/tex]
[tex]nums[3] = 3[/tex]
[tex]nums[4] = 4[/tex]
[tex]nums[5] = 5[/tex]
The next comparison is: index 3 and 4. Meaning that comparison of index 2 and 3 has been skipped.
This is so because of the way the if statement is constructed.
There are different kinds of ArrayList of integers. The option in the lists can be passed to remDups to show that the method does not work as intended is {1, 2, 2, 3, 3, 4, 5}.
When you study the different options given, one will see that that only list B has repeated duplicate numbers such as 2,2 and 3,3. while the other options have only a duplicate numbers that are not following each other.In Python, there are different ways to remove duplicates from list. An example using naive or novice method is;
The main list is : [1, 3, 5, 6, 3, 5, 6, 1]
The list after deleting duplicates : [1, 3, 5, 6]
