Answer:

64 K bytes = 65536 bytes

32 M bytes = 33554432 bytes

Explanation:

The question expect the number of bytes in binary instead of decimal. So this is important to understand that:

1K bytes = 1024 bytes (in binary)

Therefore,

64 Kb = 64 x 1024 = 65536 bytes

Using the similar calculation logic, we know

1M bytes = 1024 x 1024 = 1048576 bytes (in binary)

Therefore,

32 M bytes = 32 x 1048576 = 33554432 bytes

Suppose that, even unrealistically, we are to search a list of 700 million items using Binary Search, Recursive (Algorithm 2.1).

damaskus [11]

Answer:

There is also an attachment below

Explanation:

Since we are talking about binary search, let's assume that the items are sorted according to some criteria.

Time complexity of binary search is O(logN) in worst case, best case and average case as well. That means it can search for an item in Log N time where N is size of the input. Here problem talks about the item not getting found. So, this is a worst case scenario. Even in this case, binary search runs in O(logN) time.

N = 700000000.

So, number of comparisions can be log(N) = 29.3 = 29.

So, in the worst case it does comparisions 29 times

Mention one application of AI from the real world and describe the use of of this application what is the type of learning used

gayaneshka [121]

Answer:

The real world AI application is Google Duplex. It is able to receive orders for making reservations. Then it calls the shop or the place and deals with the person and talks to him very fluently and informs you about the reservation. Some other general types of AI application are Google Assistant, Siri , Amazon Alexa and so on. But google Duplex is lot more advanced than them.

Problem 1 (Authentication): Consider the following authentication protocol, which uses a classical cryptosystem. Alice generates

Elis [28]

Answer:

Check the explanation

Explanation:

Yes, going by the question above, the protocol validates Bob to Alice for the reason that the key is only shared between Bob and Alice as well as the number which is being sent randomly. Therefore the invader won’t be able to predict and response to that number. Because of the authentication protocol, that makes use of a classical cryptosystem thereby resulting into the possibility of an argument such that key finding is attainable via invader.

(1) prompt the user for a string that contains two strings separated by a comma. (1 pt) examples of strings that can be accepted

GalinKa [24]

package parsestrings;

import java.util.Scanner;

public class ParseStrings {

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in); // Input stream for standard input

Scanner inSS = null; // Input string stream

String lineString = ""; // Holds line of text

String firstWord = ""; // First name

String secondWord = ""; // Last name

boolean inputDone = false; // Flag to indicate next iteration

// Prompt user for input

System.out.println("Enter input string: ");

// Grab data as long as "Exit" is not entered

while (!inputDone) {

// Entire line into lineString

lineString = scnr.nextLine()

// Create new input string stream

inSS = new Scanner(lineString);

// Now process the line

firstWord = inSS.next();

// Output parsed values

if (firstWord.equals("q")) {

System.out.println("Exiting.");

inputDone = true;

if (firstWord.matches("[a-zA-Z]+,[a-zA-Z]+")) {

System.out.print("Input not two comma separated words");

}

} else {

secondWord = inSS.next();

System.out.println("First word: " + firstWord);

System.out.println("Second word: " + secondWord);

System.out.println();

}

return;

}
