Corrected Question
Write a program that reads in 15 numbers in sorted order from the user (i.e. the user enters them in order) and stores them in a 1D array of size 15. Next, prompt the user for a number to search for in the array (i.e. the "target"). Then, print the array. Next, search the array using a linear search – find the target element and printing out the target and its index as well as the entire array
Answer:
The solution is given in the explanation section
See detailed explanation of each step given as comments
Explanation:
import java.util.*;
class Main {
public static void main(String[] args) {
//Create the array of 15 elements
int [] array = new int [15];
//Create an object of the scanner class to receive user input
Scanner in = new Scanner(System.in);
//Prompt user to enter the values in sorted order
//Using a for loop
for (int i =0; i<array.length; i++){
System.out.println("Enter the next element: In SORTED order please!");
array[i] = in.nextInt();
}
System.out.println("All Fifteen element have been entered");
// Ask the user for an element to be searched for
//A target element
System.out.println("Which element do you want to search for in the array");
//Create the target element
int target = in.nextInt();
//Use a for loop to sequentially check each element in the array
for(int i = 0; i<array.length; i++){
if(array[i]==target){
System.out.println(target+" is found at index "+i +" of the array");
}
}
// Printout the entire array
System.out.println(Arrays.toString(array));
}
}
Consider a multiprocessor CPU scheduling policy. There are 2 options: 1) a singlecommon ready queue of jobs; when a CPU becomes free, the job atthe head of the queuegoes to this free CPU. 2) a ready queue for each CPU; the arriving job joins the shortestqueue. In general, do you expect the common queue or the shortest queue policy to performbetter. Justify.
Explanation:
A ready queue is more adequate since in this method the load balancing occurs in a proper way. The goal of multiple processing is the correct distribution of load.
But in the cases when a processor is doing quicker or taking a smaller queue, it will self assign processes allotted for execution, configuring it with a constant busy state.

3.What are the pros and cons of using a linked implementation of a sparse matrix, as opposed to an array-based implementation
Answer:
speed and storage
Explanation:
The pros and cons of both are mainly in regards to speed and storage. Due to linked lists elements being connected to one another it requires that each previous element be accessed in order to arrive at a specific element. This makes it much slower than an array-based implementation where any element can be quickly accessed easily due to it having a specific location. This brings us to the other aspect which is memory. Since Arrays are saved as a single block, where each element has a specific location this takes much more space in the RAM as opposed to a linked implementation which is stored randomly and as indexes of the array itself.
Array Implementation:
Pros: Much Faster and Easier to target a specific elementCons: Much More Space neededLinked Implementation
Pros: Less overall space neededCons: Much slower speed.Write a Python code to ask a user to enter students' information including name,
last name and student ID number. The program should continue prompting the
user to enter information until the user enters zero. Then the program enters
search mode. In this mode, the user can enter a student ID number to retrieve
the corresponding student's information. If the user enters zero, the program
stops. (Hint: consider using list of lists)
database = ([[]])
while True:
first_name = input("Enter the student's first name: ")
if first_name == "0":
while True:
search = input("Enter a student ID number to find a specific student: ")
if [] in database:
database.pop(0)
if search == "0":
exit()
k = 0
for w in database:
for i in database:
if i[2] == search:
print("ID number: {} yields student: {} {}".format(i[2], i[0], i[1]))
search = 0
last_name = input("Enter the student's last name: ")
id_number = input("Enter the student's ID number: ")
database.append([first_name, last_name, id_number])

def build_dictionary(string):
d = dict()
for x in string:
if not d.get(x):
d[x] = 1
else:
d[x] += 1
return d
Part 2:
Create a function named build_word_counter that has the same signature as build_dictionary. This function also returns a dictionary, however, it normalizes each word such that the case of the word is ignored (i.e. case insensitive). So the words LIKE, Like, like should be considered the same word (much like a regular dictionary would). You must use the same function add_item again (so don't make any modifications to it) Normalize words by using the lower case version of the word.
Part 3:
Create a function named build_letter_distribution that has the same signature as build_dictionary. This function returns a dictionary; however, each key will be a letter and the value will be the count that represents how many times that letter was found. Essentially you will have a letter distribution over a sentence (which is a list of words). The letters should be case insensitive.
Answer:
Follows are the code to this question:
def build_word_counter(string):#defining a method build_word_counter that accepts string as a parameter
d = dict()#defining d variable as a dictionary
for x in string:#defining for loop that use string
x = x.lower()#Use lower method
if not d.get(x):#defining if block that holds value in d variable
d[x] = 1#use dictionary to hold value in 1
else:#defining else block
d[x] += 1#use dictionary to increment value by 1
return d#return dictionary
print(build_word_counter(["Like","like","LIKE"]))#use print method to call method
def build_letter_distribution(string):#defining a method build_letter_distribution that accepts string variable
d = dict()#defining d variable as a dictionary
for i in string:#defining for loop to count string value
for j in i:#defining for loop to hold string as number
if not d.get(j):#defining if block that doesn't get value in dictionary
d[j] = 1#hold value in dictionary
else:#defining else block
d[j] += 1#use dictionary to increment the dictionary value
return d#return dictionary
print(build_letter_distribution(["Like","test","abcdEFG"]))#use print method to return its value
Output:
please find the attached file.
Explanation:
In the first program a method, "build_word_counter" is defined that accepts a string variable in its parameter, and inside the method, a dictionary variable "d" is defined that uses the for loop to hold string value and convert all value into lower case.
In the next step, a conditional statement is used that holds value in the dictionary and count its word value.
In the second program a method, "build_letter_distribution" is defined that holds string variable in its parameter, and inside the method, a dictionary variable "d" is defined that uses the two for loop and in if the block, it holds value in the dictionary and returns its value, and use print method to print its return its value.

Answer:
To create a pivot table, select the columns to pivot and click on the insert option, click on the pivot table option and select the data columns for the pivot, verify the table range, select the location for the pivot and click ok. To format a column, select the columns and click the number option on the home tab, select the currency option and click on the number of decimal places
Explanation:
Microsoft Excel is a great tool for data analysis and visualization. It has several mathematical, engineering, statistical, and graphical tools for working with data.
A pivot-table is an essential tool for describing and comparing data of different types.
The steps to follow in order to produce a Pivot table would be as mentioned below:
Opting the columns for a pivot table. Now, make a click on the insert option. This click is followed by opting for the pivot table and the data columns that are available in it.After this, the verification of the range of the table is made and then, the location for the pivot table has opted. After this, the column is formatted and the number option is selected followed by the currency option, and the quantity of decimal places. A Pivot table allows one to establish a comparison between data of distinct categories(graphic, statistical, mathematical) and elaborate them.Learn more about 'Pivot Table' here:

In this assignment you will implement a variation of Mergesort known as a bitonic mergesort, recursively.
In a normal mergesort, the input to the merge step is a single array, which is divided into two sections, both sorted ascending. We assume that the first half (0 up to but not including size/2) is the first section and the second half (size/2 up to but not including size) is the second section.
In a bitonic mergesort, we use the same arrangement, except that the second sequence is sorted in descending order: the first half goes up, and then the second half goes down. This means that when we are doing a merge, sometimes we want to merge the results into ascending order, while other times we want to merge into descending order (depending on which "half" of the final array the result will end up in). So we add another parameter, to describe the direction the output should be sorted into:
void merge(int* input, int size, int* output, bool output_asc);
If output_asc == true then after the merge output should contain size elements, sorted in ascending order. If output_asc == false, output should contain the elements sorted in descending order.
The other thing we glossed over in class was the allocation of the temporary space needed by the algorithm. It’s quite wasteful to allocate it in each recursive call: it would be better to allocate all the necessary space up front, and then just pass a pointer to it. In order to do this, we’ll write the recursive mergesort function in a helper function which will preallocate the space needed for the results:
int* mergesort(int* input, int size) {
int* output = new int[size];
mergesort(input, size, output, true);
return output;
}
void mergesort(int *input, int size, int* output, bool output_asc) {
// Your implementation here
}
The parameter output_asc serves the same purpose here as for merge: it tells the function that we want the output to be sorted ascending.
Interface
You must implement the functions
void merge(int* input, int size, int* output, bool output_asc);
int* mergesort(int* input, int size);
void mergesort(int *input, int size, int* output, bool output_asc);
Download a template .cpp file containing these definitions. This file is also available on the server in /usr/local/class/src.
merge must run in O(n) time with n= size. mergesort (both versions) must run in O(nlogn) time, and must use O(n) space. If you allocate any space other than the output array, you should free it before your function returns.
The test runner will test each function separately, and then in combination. It checks the result of sorting to make sure that it’s actually sorted, and then nothing is missing or added from the original (unsorted) sequence.
The code .cpp is available bellow
#include<iostream>

A bank has three types of accounts: checking, savings, and loan. Following are the attributes for each type of account:
CHECKING: Acct No, Date Opened, Balance, Service Charge
SAVINGS: Acct No, Date Opened, Balance, Interest Rate
LOAN: Acct No, Date Opened, Balance, Interest Rate, Payment
Assume that each bank account must be a member of exactly one of these subtypes. Using generalization, develop an EER model segment to represent this situation using the traditional EER notation, the Visio notation, or other tools like Lucidchart / Draw.io. Remember to include a subtype discriminator.
Answer:
please find the attachment of a graph:
Explanation:
Description of the model:
Generalization is the method used here just for the EER model, which sweeping generalization is a way to identify the common characteristics of a sequence to create a common entity. This is an approach from the bottom up. Its verification, savings, and credit firms are extended to a higher-level object's account. So, the entity entities (Account) are the common traits of these bodies. As well as the specific qualities are the part of specialized entities (checks, savings, and loans). This EER model is shown via the subgroup and supertype notes. The Balance has calculated the distance, throughout the entity type entity are key patterns of the subgroup entities. The wood beaded includes Acct No, Balanced and Open Date. The key was its underliner Acct No. the very first key. CHECKING, SAVINGS, and LOAN are the subsection organizations of the Supertype Account.Its subtypes get the traits that are not normal. It Testing feature is the uncommon extra fee feature. Its SAVINGS post-type feature has the peculiar exchange rate feature. Its LOAN subgroup feature produces unusual interest in fixed payment characteristics.Enhanced Entity relationships[EER] represent the requirements and complexities of a complex database.
What is Enhanced Entity-relationship?Here, the account entity generalized into three entities and these are checking, savings, and loan.
Also, the common attribute the three of them have can be considered in the account entity which is common in them while the individual attributes must be specified under its own entity.
EER models are the helpful tools used for designing databases that have high-level models.

Which type of data processing is Jason following in the transaction processing system?
A.
online decision support system
B.

C.
online office support processing
D.
online batch processing
E.
online executive processing
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is online decision support system. Because the decision support systems process the data, evaluate and predict the decision, and helps the decision-makers, and offer real time information immediately in making the decision in an organization. So the correct answer to this question is the decision supports system.
Why other options are not correct
Because the transaction processing system can only process the transaction and have not the capability to make the decision for the future. Office support processing system support office work, while the batch processing system process the task into the batch without user involvement. however, online executive processing does not make decisions and offer timely information to decision-makers in an organization.
Memory locations in personal computers are usually given in hexadecimal. If a computer programmer writes a program that requires 100 memory locations, determine the last memory location that is used if the program starts at location 2C8DH 16 hexadecimal
Answer:
The answer is "The last memory addresses used by a specific program is 2CF0".
Explanation:
For this specific problem, we assume that only a memory storage allocation like Array data structure is needed, as well as any allocation only needs one memory cell since it focuses on the structure and type of data used.
So, first, we will transform the provided memory address for better comprehension from Hexadecimal into decimal.
[tex]\to \bold{(2C8D)_{16} = (11405)_{10}}[/tex]
Now 11405 is the first memory cell's address. With all of this number, it can add 99, resulting in the final decimal memory address.
[tex]=11405 + 99\\\\= 11504[/tex]
[tex]\bold{(11504)_{10} = (2CF0)_{16}}.[/tex]

According to Darwin’s theory of evolution, differences between species may be a result of which of the following?
a) The disuse of body structures
b) The transmission of acquired characteristics
c) Natural selection
d) Mutagenic agents
Answer:
The answer is C Natural selection
Explanation:
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations
According to Darwin’s theory of evolution, differences between species may be a result of Natural selection. Thus the correct option is C.
What is Darwin’s theory of evolution?According to Darwin, all species descended from a single ancestor, species can change through time, and new species can arise from existing ones which makes them interconnected with common traits.
Natural selection of traits in a species that would help the species in its survival is the process that drives diversification, the evolutionary process through which new biological species form.
Natural selection is the evolutionary mechanism stating that with many resources available in nature, creatures with genetically inherited features that promote survival and reproduction will typically produce more offspring than their conspecific competitors.
Therefore, option C is appropriate.

In Python
Write the special method __str__() for CarRecord.
Sample output with input: 2009 'ABC321'
Year: 2009, VIN: ABC321
Answer:
def __str__(self):
return ('Year: %d, VIN: %s' %(self.year_made, self.car_vin))
Explanation:
Here you go! This should do it.
The program gives an implementation of the car record class which displays the model year and registration number of a car. The program written in python 3 goes thus :
class CarRecord :
#initialize a class named carRecord
def __init__(self):
#define the init method of the class
self.year_made = 0
#year car was made is initialized to 0 (integer)
self.car_vin = ' '
#vehicle registration is an empty string
def __str__(self):
#define an str method
return f"Year:{self.year_made}, VIN:{self.car_vin}"
#returns formatted display of the year and VIN number
my_car = CarRecord()
#creates an instance of the carRecord class
my_car.year_made = int(input())
#prompts user for the model year of the car
my_car.car_vin = input()
#prompts user for the model Vin number
print(my_car)
# display the details
A sample run of the program is given
