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]

An analogue sensor has a bandwidth which extends from very low frequencies up to a maximum of 14.5 kHz. 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
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]

The third assignment involves writing a Python program to compute the cost of carpeting a room. Your program should prompt the user for the width and length in feet of the room and the quality of carpet to be used. A choice between three grades of carpeting should be given. You should decide on the price per square foot of the three grades on carpet. Your program must include a function that accepts the length, width, and carpet quality as parameters and returns the cost of carpeting that room. After calling that function, your program should then output the carpeting cost.
Your program should include the pseudocode used for your design in the comments. Document the values you chose for the prices per square foot of the three grades of carpet in your comments as well.
You are to submit your Python program as a text file (.txt) file. In addition, you are also to submit a test plan in a Word document or a .pdf file. 15% of your grade will be based on whether the comments in your program include the pseudocode and define the values of your constants, 70% on whether your program executes correctly on all test cases and 15% on the completeness of your test report.
Answer:
# price of the carpet per square foot for each quality.
carpet_prices=[1,2,4]
def cal_cost(width,height,choice):
return width*height*carpet_prices[choice-1]
width=int(input("Enter Width : "))
height=int(input("Enter Height : "))
print("---Select Carpet Quality---")
print("1. Standard Quality")
print("2. Primium Quality")
print("3. Premium Plus Quality")
choice=int(input("Enter your choice : "))
print(f"Carpeting cost = {cal_cost(width,height,choice)}")
Explanation:
The cal_cost function is used to return the cost of carpeting. The function accepts three arguments, width, height, and the choice of carpet quality.
The program gets the values of the width, height and choice, calls the cal_cost function, and prints out the string format of the total carpeting cost.

Your first submission for the CIS 210 Course Project should include the following functionality: - Requests the user to input his/her first name - Formats the name to capitalize the first letter and makes all remaining characters lowercase, removing any spaces or special characters - Output the formatted name to the console
Answer:
In Java:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String name;
System.out.print("First name: ");
name = input.next();
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
System.out.print(name);
}
}
Explanation:
This declares name as string
String name;
This prompts the user for first name
System.out.print("First name: ");
This gets the name from the user
name = input.next();
This capitalizes the first letter of name and makes the other letters to be in lowercase
name= name.substring(0, 1).toUpperCase() + name.substring(1).toLowerCase();
This prints the formatted name
System.out.print(name);

As you will solve more complex problems, you will find that searching for values in arrays becomes a crucial operation. In this part of the lab, you will input an array from the user, along with a value to search for. Your job is to write a C++ program that will look for the value, using the linear (sequential) search algorithm. In addition, you should show how many steps it took to find (or not find) the value, and indicate whether this was a best or worst case scenario (... remember the lecture). You may refer to the pseudo-code in the lecture, but remember that the details of the output and error conditions are not specified there. Also, note that in pseudo-code arrays are sometimes defined with indices 1 to N, whereas in C++ the indexes span from 0 to N-1.
The program will work as follows. First, you should ask the user to enter the size of the array, by outputting:
"Enter the size of the array: "
to the console. If the user enters an incorrect size, you should output the error message:
"ERROR: you entered an incorrect value for the array size!"
and exit the program. If the input is a valid size for the array, ask the user to enter the data, by outputting
"Enter the numbers in the array, separated by a space, and press enter: "
Let the user enter the numbers of the array and store them into a C++ array. Up to now, this should be exactly the same code as Lab#2. Next, ask the user a value v to search for in the array (called the "key"), by outputting:
"Enter a number to search for in the array: " to the screen, and read the key v.
Search for v by using the linear search algorithm. If your program finds the key, you should output:
"Found value v at index i, which took x checks. "
where i is the index of the array where v is found, and x is the number of search operations taken place.
If you doesn't find the key, then output: "
The value v was not found in the array!"
Then indicate whether you happened to run into a best or worst case scenario. In case you did, output: "
We ran into the best case scenario!" or "We ran into the worst case scenario!"
otherwise, don't output anything.
Answer:
#include<iostream>
using namespace std;
int main() {
cout<<"Enter The Size Of Array: ";
int size;
bool isBestCase=false;
cin>>size;
if(size<=0){
cout<<"Error: You entered an incorrect value of the array size!"<<endl;
return(0);
}
int array[size], key;
cout<<"Enter the numbers in the array, separated by a space, and press enter:";
// Taking Input In Array
for(int j=0;j<size;j++){
cin>>array[j];
}
//Your Entered Array Is
for(int a=0;a<size;a++){
cout<<"array[ "<<a<<" ] = ";
cout<<array[a]<<endl;
}
cout<<"Enter a number to search for in the array:";
cin>>key;
for(i=0;i<size;i++){
if(key==array[i]){
if(i==0){
isBestCase=true; // best case scenario when key found in 1st iteration
break;
}
}
}
if(i != size){
cout<<"Found value "<<key<<" at index "<<i<<", which took " <<++i<<" checks."<<endl;
} else{
cout<<"The value "<<key<<" was not found in array!"<<endl;
cout<<"We ran into the worst-case scenario!"; // worst-case scenario when key not found
}
if(isBestCase){
cout<<"We ran into the best case scenario!";
}
return 0;
}
Explanation:
The C++ source dynamically generates an array by prompting the user for the size of the array and fills the array with inputs from the user. A search term is used to determine the best and worst-case scenario of the created array and the index and search time is displayed.

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
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
You want to make access to files easier for your users. Currently, files are stored on several NTFS volumes such as the C:, D:, and E: drives. You want users to be able to access all files by specifying only the C: drive so they don't have to remember which drive letter to use. For example, if the accounting files are stored on the D: drive, users should be able to access them using C:\accounting. What can you do?
Answer:
volume mount points
Explanation:
The best thing to do would be to use volume mount points. This is a feature that allows you to mount/target (from a single partition) another folder or storage disk that is connected to the system. This will easily allow the user in this scenario to access the different files located in the D: and E: drive from the C:\ drive itself. Without having to go and find each file in their own separate physical drive on the computer.
