The best structures to create the following items are
ARRAYHASHMAPS QUEUE SORTED LINK LISTSExplanation:
The best structures to create the following items are:
Array : for the storage of cards in a card game the best data structure to be used should be the Array data structure. this is because the size of the data ( 52 cards ) is known and using Array will help with the storing of the cards values in the Game.Hashmaps : Hashmap data structure should be implemented in online shopping cart this IS BECAUSE items can be easily added or removed from the cart therefore there is a need to map the Items ID or name to its actual database online waiting list are usually organised/arranged in a first-in-first-out order and this organization is best created using the queue data structure Sorted link lists is the best data structure used to create, store and manage online tickets. the sorted link data structure helps to manage insertions and deletions of tickets in large numbers and it also reduces the stress involved in searching through a large number of tickets by keeping the tickets in sorted listsa. A programmer wrote a software delay loop that counts the variable (unsigned int counter) from 0 up to 40,000 to create a small delay. If the user wishes to double the delay, can they simply increase the upperbound to 80,000?
b. If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Answer:
Explanation:
The objective here is to determine if the programmer can simply increase the upperbound to 80,000.
Of course Yes, The programmer can simply increase the delay by doubling the upperbound by 80000. The representation can be illustrated as:
( int : i = 0; i < 40,000; i ++ )
{
// delay code
}
Which can be modified as:
( int : i = 0; i < 80,000; i ++ )
{
// delay code
}
b) If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Assuming there is no delay being created at the run-time,
The code is illustrated as:
For ( int : i = 0 ; i < 0 ; i ++ )
{
// delay code which wont
//execute since code delay is zero
}
we ought to check whether the loop is being satisfied or not. At the Initial value of loop variable, is there any break or exit statement is being executed in between loop. Thus, the aforementioned delay loop wont be executed since the loop wont be executed for any value of i.
Numbering exception conditions, which often uses hierarchical numbering, in a fully developed use case description is helpful to _______. a. tie the exception condition to a processing step b. show which exception conditions are subordinate to other exceptions c. provide an identifier for each exception condition d. tie exception conditions to other diagrams or descriptions
Answer:
a) tie the exception condition to a processing step
Explanation:
Numbering exception conditions, in a fully developed use case description is helpful to tie the exception condition to a processing step
The fully developed use case description is useful for the documentation of the context, purpose, description, conditions, and workflow of each use case. Activity diagrams give a graphical image of the use case workflow and serve the purpose of illustrating the alternative paths through a business process.
Suppose you have 9 coins and one of them is heavier than others. Other 8 coins weight equally. You are also given a balance. Develop and algorithm to determine the heavy coin using only two measurements with the help of the balance. Clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
Answer:
Following are the algorithm to this question:
Find_Heavier_Coins(Coin[9]):
i) Let Coin[] Array represent all Coins.
ii) Divide coin[] into 3 parallel bundles and each has three coins, example 0-2, 3-5, 6-8 indicate a1 a2 a3
iii) Randomly select any two bundles and place them in balance [say a1 and a2]
iv) If Weigh of a1 and a2 has same:
// checking that if a3 has heavier coin
Choose any two 6-8 coins and place them onto balance [say 6 and 8]
If those who weigh has the same weight:
Third coin is coin heavier [say 7]
else:
The coin [6 or 8] is the one which is heavier on the balance
else:
//The coin has the package which would be heavier on the balance [say a1]
Select any two coins on balance from of the heavier package [say 0 and 1]
If they weigh the same weight:
Third coin is coin heavier [say 2]
else:
The coin that is heavier on the balance is the [or 0]
Explanation:
In the above-given algorithm code, a method Find_Heavier_Coins is declared which passes a coin[] array variable in its parameters. In the next step, if conditional block is used that checks the values which can be described as follows:
In the first, if block is used that checks a1 and a2 values and uses another if block in this it will print a3 value, else it will print 6 to 8 value. In the another, if the block it will check third coins value and prints its value if it is not correct it will print first coin valueWrite a C++ program to find if a given array of integers is sorted in a descending order. The program should print "SORTED" if the array is sorted in a descending order and "UNSORTED" otherwise. Keep in mind that the program should print "SORTED" or "UNSORTED" only once.
Answer:
The cpp program for the given scenario is as follows.
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
//boolean variable declared and initialized
bool sorted=true;
//integer array declared and initialized
int arr[] = {1, 2, 3, 4, 5};
//integer variables declared and initialized to length of the array, arr
int len = std::end(arr) - std::begin(arr);
//array tested for being sorted
for(int idx=0; idx<len-1; idx++)
{
if(arr[idx] < arr[idx+1])
{
sorted=false;
break;
}
}
//message displayed
if(sorted == false)
cout<< "UNSORTED" <<endl;
else
cout<< "UNSORTED" <<endl;
return 0;
}
OUTPUT
UNSORTED
Explanation:
1. An integer array, arr, is declared and initialized as shown.
int arr[] = {1, 2, 3, 4, 5};
2. An integer variable, len, is declared and initialized to the size of the array created above.
int len = std::end(arr) - std::begin(arr);
3. A Boolean variable, sorted, is declared and initialized to true.
bool sorted=true;
4. All the variables and array are declared inside main().
5. Inside for loop, the array, arr, is tested for being sorted or unsorted. The for loop executes over an integer variable, idx, which ranges from 0 till the length of the array, arr.
6. The array is assumed to be sorted if all the elements of the array are in descending order.
7. If the elements of the array are in ascending order, the Boolean variable, sorted, is assigned the value false and for loop is exited using break keyword. The testing is done using if statement.
8. Based on the value of the Boolean variable, sorted, a message is displayed to the user.
9. The program can be tested for any size of the array and for any order of the elements, ascending or descending. The program can also be tested for array of other numeric data type including float and double.
10. All the code is written inside the main().
11. The length of the array is found using begin() and end() methods as shown previously. For this, the iterator header file is included in the program.

Universal Containers has two customer service contact centres and each focuses on a specific product line. Each contact centre has a varying call volume, contributing to a high operational cost for the company. Universal Containers wants to optimize the cost without compromising customer satisfaction.; What can a consultant recommend to accomplish these objectives?
A. Prioritize customer calls based on their SLA
B. Cross-train agents on both product lines
C. Enable agents to transfer calls to other agents
D. Implement a customer self-service portal
Answer:
B. Cross-train agents on both product lines
D. Implement a customer self-service portal
Explanation:
Cross-training is a way of teaching employees different aspects of the job so that they can have a measure of flexibility in the discharge of duties. Managers find this approach to be effective as they believe it saves cost and maximizes the usefulness of employees. It also helps to serve and satisfy a wider range of customers.
So for Universal Containers seeking to optimize cost without compromising customer satisfaction while managing two customer service contact centers, an effective way of dealing with the large call volumes is cross-training agents on both product lines so that they can attend to a wider range of customers. Cross-training agents on both product lines would make them more knowledgeable of the services being offered and this would minimize the need to transfer calls as all agents can provide information on the various products.
Implementing a customer self-service portal would also reduce the workload on the customer service agents as customers can access the information they need on their own.
Write a function called unzip that takes as parameter a sequence (list or tuple) called seq of tuples with two elements. The function must return a tuple where the first element is a list with the first members of the seq tuple and the second element is a list with the second members of the seq tuple.
This example clarifies what is required:
Ist =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(Lst) lst tup
print(tup)
#prints ([1, 2, 3], ['one', two','three'7)
Answer:
Here is the function unzip:
def unzip(lst):
result= zip(*lst)
return list(result)
The complete program in Python is given below:
def unzip(lst):
result= zip(*lst)
return list(result)
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
Explanation:
Here zip() function is used in the unzip function. The return type of zip() function is a zip object. This means the function returns the iterator of tuples. This function can be used as its own inverse by using the * operator.
If you do not want to use zip() function then the above program can also be implemented as following which uses a for loop for elements in the given list (lst). This can make a pair of lists (2 tuple) instead of list of tuples:
def unzip(lst):
output = ([ a for a,b in lst ], [ b for a,b in lst ])
return output
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
The programs along with their output are attached.
Write a program that displays the following pattern: ..\.\* .\.\*** \.\***** ******* \.\***** .\.\*** ..\.\* That is, seven lines of output as follows: The first consists of 3 spaces followed by a star. The second line consists of 2 spaces followed by a 3 stars. The third consists of one space followed by 5 stars, and the fourth consists just of 7 stars. The fifth line is identical to third, the sixth to the second and the seventh to the first. Your program class should be called StarPattern
Answer:
public class StarPattern {
public static final int MAX_ROWS = 7;
public static void main(String []args){
for (int row = 1; row <= MAX_ROWS; row++) {
int numOfSpaces = getNumberOfSpaces(row);
int numOfStars = MAX_ROWS - (getNumberOfSpaces(row) * 2);
String spaces = printSpaces(numOfSpaces);
String stars = printStars(numOfStars);
System.out.println(spaces + stars);
}
}
public static int getNumberOfSpaces(int row) {
int rowOffset = (MAX_ROWS / 2) + 1;
return Math.abs(row-rowOffset);
}
public static String printSpaces(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += " ";
}
return result;
}
public static String printStars(int num) {
String result = "";
for (int i = 0; i < num; i++) {
result += "*";
}
return result;
}
}
Explanation:
So it sounds we need to make a diamond shape out of asterisks like this:

There are 7 rows and each row has up to 7 characters. The pattern is also symmetrical which makes it easier. Before writing any code, let's figure out how we are going to determine the correct amount of spaces we need to print. There are a lot of ways to do this, but I'll just show one. Let's call the 4th row y=0. Above that we have row 3 which would be y=-1, and below is row 5 which is y=1. With 7 rows, we have y=-3 through y=3. The absolute value of the y value is how many spaces we need.
To determine the number of stars, we just double the number of spaces, then subtract this number from 7. This is because we can imagine that the same amount of spaces that are printed in front of the stars are also after the stars. We don't actually have to print the second set of spaces since it is just white space, but the maximum number of characters in a row is 7, and this formula will always make sure we have 7.
I hope this helps. If you need help understanding any part of the code, jsut let me know.

How effectively would a priority-based scheduling algorithm handle this situation if one run queue had all high-priority threads and a second queue had all low-priority threads
Answer and Explanation:
Consider giving greater priority to both the queue contains the national priority comment section as well as, therefore, first method the thread throughout this queue.If the item from either the major priority queue becomes decoupled, if the balancing between some of the number of comments in some of these two queues becomes disrupted, instead decouple one thread from either the queue comprising the low-value thread as well as position that one in the queue with the highest - priority loop to match the number of connections in such 2 queues.Whenever a new thread arrives with some kind of proper description, a friendly interface could've been introduced to just the queue contains fewer threads to achieve stability.Therefore, the load-balancing requirements for keeping about the same number of threads would be retained and the meaningful matter of top priority thread would also be retained.
Based on the information given, it is important to give higher priority to the queue that contains the high priority thread.
Also, once an element from the high priority queue is dequeued, then dequeue one thread from the queue containing low priority thread and this will be enqueued into the queue having high priority thread in order to balance the number of threads.
Since the priority queue automatically adjusts the thread, hence the removal of the thread from one priority queue to another is not a problem.

Account Balance Design a hierarchy chart or flowchart for a program that calculates the current balance in a savings account. The program must ask the user for:________.
A- The starting balance
B- The total dollar amount of deposits made
C- The total dollar amount of withdrawals made
D- The monthly interest rate
Once the program calculates the current balance, it should be displayed on the screen.
Answer:
a. starting balance
Explanation:
A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.

For an input array with 1000 rows and 512 columns, the algorithm takes 173 ms.
We want to find out how long will the algorithm take to run on an input array with 1500 rows and 4096 columns?
Let the algorithm take x ms to run 1500 rows and 4096 columns.
For an input of n rows and m columns, it takes
[tex]n \: log_{2} \:m[/tex]
So,
[tex]1000 \: log_{2} \:512 = 173 \\\\1000 \: log_{2} \:2^{9} = 173 \:\:\: ( 2^{9} = 512) \\\\1000 \times 9 = 173 \:\:\:\:\: \: \: eg. 1[/tex]
and
[tex]1500 \: log_{2} \:4096 = x \\\\1500 \: log_{2} \:2^{12} = x \:\:\: ( 2^{12} = 4096) \\\\1500 \times 12 = x \:\:\:\:\: \: \: eg. 2[/tex]
Now divide the eq. 2 by eq. 1 to find the value of x
[tex]\frac{1500 \times 12}{1000 \times 9} = \frac{x}{173} \\\\\frac{18000 }{9000} = \frac{x}{173} \\\\2 = \frac{x}{173} \\\\x = 2 \times 173 \\\\x = 346 \: ms[/tex]
Therefore, the algorithm takes 346 ms to run on an input array with 1500 rows and 4096 columns.
If a large organization wants software that will benefit the entire organization—what's known as enterprise application software—the organization must develop it specifically for the business in order to get the functionality required.
Answer:
Hello your question lacks the required options which is : True or False
answer : TRUE
Explanation:
If a large organization wants to develop a software that will benefit the entire organization such software will be known as an enterprise application software and such application software must be developed in such a way that it meets the required purpose for which the organization is designed it for.
An enterprise application software is a computer software developed specially to satisfy the specific needs of an entire organization inside of the individual needs of the people working in the organization.
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
Answer: Provided in the explanation section
Explanation:
The Question says;
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
The Answer (Explanation):
XOR, exclusive OR only gives 1 when both the bits are different.
So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND
with 00000000 would also give 0,
but it would give 0 with all the inputs, not just 10000001.
Cheers i hope this helped !!
During an investigation of a cybercrime, the law enforcement officers came across a computer that had the hard drive encrypted. Chose the best course of action they should take to access the data on that drive.
a. Use image filtering techniques to see what's behing the encrypted files.
b. Try to convince the owner of the computer to give you to decryption key/password.
c. Identify the encryption algorithm and attempt a brute force attack to get access to the file.
d. Disconnect the hard drive from power so the encryption key can be exposed on the next power up.
e. Try to copy the drive bit by bit so you can see the files in each directory.
Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
Create an empty list called resps. Using the list percent_rain, for each percent, if it is above 90, add the string ‘Bring an umbrella.’ to resps, otherwise if it is above 80, add the string ‘Good for the flowers?’ to resps, otherwise if it is above 50, add the string ‘Watch out for clouds!’ to resps, otherwise, add the string ‘Nice day!’ to resps. Note: if you’re sure you’ve got the problem right but it doesn’t pass, then check that you’ve matched up the strings exactly.
Answer:
resps = []
percent_rain = [77, 45, 92, 83]
for percent in percent_rain:
if percent > 90:
resps.append("Bring an umbrella.")
elif percent > 80:
resps.append("Good for the flowers?")
elif percent > 50:
resps.append("Watch out for clouds!")
else:
resps.append("Nice day!")
for r in resps:
print(r)
Explanation:
*The code is in Python.
Create an empty list called resps
Initialize a list called percent_rain with some values
Create a for loop that iterates through the percent_rain. Check each value in the percent_rain and add the required strings to the resps using append method
Create another for loop that iterates throgh the resps and print the values so that you can see if your program is correct or not
Answer:
resps = []
for i in percent_rain:
if i > 90:
resps.append("Bring an umbrella.")
elif i >80:
resps.append("Good for the flowers?")
elif i > 50:
resps.append("Watch out for clouds!")
else:
resps.append("Nice day!")
Explanation:
The main() module in the starter code below takes integar inputs separated by commas from the user and stores them in a list. Then, it allows the user to manipulate the list using 3 functions:
mutate_list() takes 3 parameters -- a list, index number, and a value -- and inserts the value in the position specified by the index number in the list.
remove_index() takes 2 parameters -- a list and an index number -- and remove the element at the position number indicated by index. It also prints the total number of elements in the list before and after removing the character in this fashion:"Total elements in list = 11
Total elements in list = 10"
reverse_list() takes 1 parameter -- a list -- and returns the list reversed.
Examples:
Example 1:
Enter values in list separated by commas: 1,2,4,63,6,4,22,53,76
[1, 2, 4, 63, 6, 4, 22, 53, 76]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m,r,R): m
4,45
[1, 2, 4, 63, 45, 6, 4, 22, 53, 76]
Example 2:
Enter values in list separated by commas: 1,2,4,6,84,3,2,2,76
[1, 2, 4, 6, 84, 3, 2, 2, 76]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m,r,R): R
[76, 2, 2, 3, 84, 6, 4, 2, 1]
Example 3:
Enter values in list separated by commas: 12,2,3,5,2,6,2,1,2,333,65
[12, 2, 3, 5, 2, 6, 2, 1, 2, 333, 65]
Menu:
mutate list(m), remove (r), reverse_list (R)
Enter choice (m,r,R): r
Example 4
Total elements in list = 11
Total elements in list = 10
[12, 2, 3, 5, 6, 2, 1, 2, 333, 65]
please use the codes below
def main():
user_list = input("Enter values in list separated by commas: ")
user_list = user_list.split(",")
user_list = [int(i) for i in user_list]
print(user_list)
print("Menu: ")
print("mutate list(m), remove (r), reverse_list (R)")
user_choice = input("Enter choice (m,r,R): ")
if user_choice == 'm':
index_num, v = input().split(",")
index_num = int(index_num)
v = int(v)
mutate_list(user_list, index_num, v)
print(user_list)
elif user_choice == 'r':
index_num = int(input())
remove_index(user_list, index_num)
print(user_list)
elif user_choice == 'R':
new_list = reverse_list(user_list)
print(new_list)
