Perform algorithm time measurement for all three quadratic sorting algorithms for Best Case (already sorted), Average Case (rand

omly generated), and Worst Case (inverse sorted) inputs and compare them with O(N*logN) sorting algorithm using Arrays.sort() method. Use arrays sizes of 50K, 100K, and 200K to produce timing results.

Best case : 1.259

Bubble sort:

--------------------------------------------------------

Worst case : 1.990

Average case : 2.009.

Best case : 1.950

Explanation:

[NB: since it is very long there is the need for me to put it it a document form. Kindly check the doc. Files. The file A is the sort Analysis.Java file and the file B is the sort.Java file].

The concept of algorithm time measurement strictly depends on the following;

=> The measurement of time, space or energy on different sizes.

=> Plotting of the measurements and characterizing them.

=> Running or implementation of the algorithm.

Programming language such as Java can be used in accessing the operating system clock and Java had two static methods.

KINDLY CHECK BELOW FOR THE ATTACHMENT.

tia_tia [17]

Answer:

True

Explanation:

It is TRUE that An Information System is the set of steps that need to be followed to ensure that software development proceeds in an orderly fashion.

This is evident in the fact that the Information system involves various stages and different elements such as data, people, procedures, hardware, and software.

All these elements form together to create several steps in software development in a suitable manner that meets the clients' and customers' needs.

An early attempt to force users to use less predictable passwords involved computer-supplied passwords. The passwords were eight
Sedaia [141]

Answer:

Recently, with the new and advanced hacking algorithms and affordable high-performance computers available to adversaries, the 36 character computer suggested passwords can easily be insecure.

Explanation:

The 8 length passwords generated pseudo-randomly by computers are not secure as there are new algorithms like the brute force algorithm that can dynamically obtain the passwords by looping through the password length and comparing all 36 characters to get the right one.

And also, the use of high-performance computers makes these algorithms effective

What are the similarities and differences between the binary and decimal systems?
maks197457 [2]

Answer:

A binary system is a system that functions on zeros and ones (0's and 1's).

A decimal system is an Arabic numeric system that has 10 as its base and uses a dot which is also called a decimal point to show fractions.

Differences

  • A decimal uses ten different digits which is 0-9 while a binary system uses just two digits 0 and 1
  • Decimal system was historically a Hindu-Arabic system while the binary system is just an Arabic system

Similarities

  • They are capable of performing arithmetic operations
  • They both can be represented in decimal form

xz_007 [3.2K]

Answer:

see explaination

Explanation:

import java.io.*;

import java.util.Scanner;

public class Winners {

public static void main(String args[]) throws IOException {

Scanner sc = new Scanner(new File("WorldSeriesWinners.txt"));

String commands[] = new String[100000];

int c = 0;

while (sc.hasNextLine()) {

String input = sc.nextLine();

System.out.println(input);

if (input.isEmpty())

continue;

commands[c++] = input;

}

sc.close();

Scanner keyboard = new Scanner(System.in);

System.out.println("Enter the name of a team: ");

String name = keyboard.nextLine();

int count = 0;

for (int i = 0; i < c; i++) {

if (commands[i] != null) {

if (commands[i].equals(name)) {

++count;

}

}

}

if(count!=0)

System.out.println(name + " has won the World Series in the time period from 1903 through 2018 " +count + " number of times" );

else

System.out.println("Team with name "+name+ " does not exists");

}

}
