. The add() method of the ArrayList class can: A. Shift indexes in the list B. Creates a new Value at the end of the list C. Creates a new Value at any specified index D. Increases the size of the list E. All of the Above
Answer:
All of the Above
Explanation:
The add() method of the ArrayList class is a Java function that jas the capability of adding elements to an array list. In order to add elements to the great list, this java function does the following work as well
1. It shift indexes in the list
2. It establishes a new Value at the end of the list
3. It creates a new Value at any specified index
4. It expands the size of the list.
Hence, in this case, the correct answer is option E. "All of the above."
Let us consider the easiest sorting algorithms – Maxsort. It works as follows: Find the largest key, say max, in the unsorted section of array (initially the whole array) and then interchange max with the element in the last position in the unsorted section. Now max is considered part of the sorted section consisting of larger keys at the end of the array. It is no longer in the unsorted section. Repeat this until the whole array is sorted. a) Write an algorithm for Maxsort assuming an array E contains n elements to be sorted, with indexes 0, 1,…,n-1. b) How many comparisons of keys does Maxsort do in the worst case and on average? Submit source code, test cases, results, and the answers to part (b)
Answer:
count = 0
for x in range(len(array)):
if count == Len(array) -1:
break
max = max(array[:-1 - count])
count += 1
if array.index(max) == -1:
break
else:
hold = array[-1]
array[-1] = max
array[array.index(max)] = hold
Explanation:
The python program is an implementation of a maxsort. The for loop iterates over the array, getting the maximum number for each reduced array and swaps it with the corresponding last items.
Cryptocurrencies are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. Which other instrument could most reasonably fulfill the same function
Answer:
Gold
Explanation:
From the question, we are informed about Cryptocurrencies which are digital tokens that are created independently of government money, and can act as a medium of exchange and store of value. One of other instrument that could most reasonably fulfill the same function is Gold. A medium of exchange can be regarded as a intermediary instrument which is a function of money that facilitate trade or purchase and selling between seller and buyers, and it must be accepted as payment for transactions. Such intermediary instrument as a medium of exchange are Gold, salt as well as stone. Gold was chosen by most of the commodity-money advocates as a medium of exchange as a result of the intrinsic property it posses, and it's fixed stock value
Write a C++ program to define an abstract class in polymorphism?
Answer:
Following are the program to this question:
#include <iostream>//header file
using namespace std;//namespace
class Val //defining abstract class
{
public://use access specifier
virtual int squ()=0;//declaring a method squ
void setval(int x) //defining a method setval
{
a=x;//holding value in a variable
}
protected://use access specifier
int a;//defining integer variable
};
class square: public Val //defining a class square that inherit abstract class
{
public://use access specifier
int squ() //defining squ method
{
return (a*a); //return square value
}
};
int main() //main method
{
square s;//creating class object
s.setval(5);//calling setval method
cout << "The square value is: " << s.squ() << endl;//print value by calling squ method
}
Output:
The square value is: 25
Explanation:
In the above code a two-class "Val and square" is declared, in which val is abstract class, in a method squ is declared, and setval is used to set the value.
In the next step, the square class inherits Val and defines the squ method, and uses the return keyword to return its calculated value.
In the main method square class object is created and set the setval value and call the squ method and print its value.

PLS HELP: Identify the correct CSS syntax to link an external style sheet??
Answer:
See Explanation
Explanation:
This question required options. Since there are none, I'll answer on a general terms.
To link to an external style sheet in CSS, use the following syntax:
<link rel = "stylesheet" type = "text/css" href = "link to css file">
As seen above, the link tag is used to achieve this tax.
The rel attributes shows the relationship between the css file and the html file.
In this case, the css file is a stylesheet; hence, rel = "stylesheet"
Next, is the type attribute which shows the content of the file to be linked. In other words, the file type
Lastly, the link to the css file.
Take for instance, the file name is example.css and it is in the same directory as the current document, the following will be used.
href = "example.css"
However, if example.css is in a different directory, the link to the file directory will be stated.
Conclusively, one syntax to use for a file named example.css is:
<link rel = "stylesheet" type = "text/css" href = "exampl.css">

Explanation:
PYTHONSorting TV Shows (dictionaries and lists)Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons).Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.Ex: If the input is:file1.txtand the contents of file1.txt are:20Gunsmoke30The Simpsons10Will & Grace14Dallas20Law & Order12Murder, She Wrotethe file output_keys.txt should contain:10: Will & Grace12: Murder, She Wrote14: Dallas20: Gunsmoke; Law & Order30: The Simpsonsand the file output_titles.txt should contain:DallasGunsmokeLaw & OrderMurder, She WroteThe SimpsonsWill & Grace
Answer:
with open("file1.txt", "r") as file:
lines = file.readlines()
mydict = dict()
for x in range(0, len(lines) - 1, 2):
mydict[lines[x]] = lines[x-1]
dict_keys = sorted(mydict.keys)
sorted_dict ={}
for key in dict_keys:
sorted_dict[key] = mydict[key]
with open("output_keys.txt", "a+") as writn:
for key, value in sorted_dict.items():
writn.write(key: value)
writn.write("\n")
dict_values = sorted(mydict.values)
with open("output_titles", "a+") as title:
for name in dict_values:
title.write(name)
title.write("\n")
Explanation:
The python program above reads in the file context, files.txt, and creates a dictionary of the file with the number of seasons as the key and movie title as the value. The sorted dictionary is saved in the output_keys.txt file and the titles in output_titles.txt file.
A Web server has five major components that must all function in order for it to operate as intended. Assuming that each component of the system has the same reliability and one of the components will have a backup with a reliability equal to that of any one of the other components, what is the minimum reliability each one must have in order for the overall system to have a reliability of 0.696
Answer:
The answer is below
Explanation:
Let x represent the reliability of each of the five major components. Since all the components must function before the system operates, hence they are in series with each other.
One component has a backup of the same reliability, the reliability of the back up system = 1 - (1 - x)² = 2x - x²
Therefore the reliability of the system is:
x * x * x * x * (2x - x²) = 0.696
2x⁵ - x⁶ = 0.696
x⁶ - 2x⁵ + 0.696 = 0
Solving the polynomial equation online using byjus.com gives:
x = 0.915038
x = 1.97695
x = -0.632585 - 0.429075 i
x = -0.632585 + 0.429075 i
x = 0.186590 - 0.789741 i
x = 0.186590 + 0.789741 i
Since the reliability is not a complex number and it is less than or equal to 1, hence:
x = 0.915038, x ≅ 0.915

Answer:
Local fisherman recover the body of Major Martin off the coast of Spain .Spanish officials pass off the information in the briefcase to German agents.Major Martin's name appears on a casualty list in a British newspaper.Germany prepares for an imminent attack on the island of Sardinia.Explanation:
This above is the order in which Operation Mincemeat was executed in WW2 to deceive the Germans into believing that the Allies were going to invade the Balkans directly instead of Sicily which was their actual target.
The plan involved a fictitious Major Martin who had secret documents about the Allied invasion of the Balkans. After the body was released from a British submarine, it washed up in Spain where it was found by local fishermen.
Spanish officials then passed the information in the briefcase Major Martin had to German intelligence. To further reinforce the ruse, the British published Major Martin's name in a casualty list.
The Germans were thoroughly convinced and switched forces from Sicily for the defence of the Balkans and the island of Sicily.

Assume you have the all_info list that is given in the Do It Now problem 1. This list includes the grades of 4 courses for 4 students. Write a code that asks a name from the user. Then it will search for that name in the list all info. Of the name exists in the list, the program will display the programming grade of that student. For example, if the user enters 'Sarah ' the program will display 90. If the user enters a name that is not in the list, such as 'Jack', the program will display an error message such as 'Sorry, but this student is not in the list'.
Answer:
titles =['name', 'physics', 'chemistry', 'math', 'programming']
student_1 =['Kathy', 90, 80, 75, 100]
student_2 =['John', 65, 84, 79, 90]
student_3 =['Joe', 45, 89, 100, 10]
student_4 =['Sarah', 68, 89, 93, 90]
all_info =[titles, student_1, student_2, student_3, student_4]
student = input("Enter student's name: ")
student_list = [name[0] for name in all_info]
if student in student_list:
print(all_info[student_list.index(student)][4])
if student not in student_list:

The key operation in encryption and decryption process is the exponentstion. Given an integer x it is easy to write a linear algo O((n)) to find x^n for any integer n. Describe the maths of a fast exponentation algo that can compute x^n in o(log2n) time. Justify
Answer:
Following are the solution to this question:
Explanation:
[tex]x^n[/tex] could be approximated by getting a small n loop as well as multiplying x for each incarnation in a linear time. It's very simple. Its key concept is to do it in log2n time.
[tex]x^n = x^{\frac{n}{2}}\ is \ obvious \ \ x^{\frac{n}{2}}[/tex]
Therefore,[tex]x^{n}, x^{\frac{n}{2}}[/tex] could be determined and divided by itself instead of [tex]x^n[/tex] calculation. It must be done frequently to ensure which half the research is done out with each stage.
Runtime:
Its repetition relationship of the above function is:
[tex]T(n) = T(\frac{n}{2}) + 1[/tex]
This can be resolved by master theorem, so it's obvious. The running time of this repeating ration, by master theorem, is [tex]O ( \log_2n )[/tex].
Pseudocode:
int exponent( int x_1, int y_1 )//defining a method exponent
{
if(y_1==1) //use if to check n value equal to 1
{return x_1;} //return x value
Int t= exponent(x_1,y_1/2);//call method
return t*t;//calculate square
