You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types.
What you need to do?
1. Writing detailed comments and docstrings
2. Organizing and structuring code for readability
3. URL = :///
Steps for Completion
Task
Create two lists of strings - one list for Protocol called valid_protocols, and one list for storing File extension called valid_ftleinfo . For this take the protocol list should be restricted to http , https and ftp. The file extension list should be hrl. and docx CSV.
Split an input named url, and then use the first element to see whether the protocol of the URL is in valid_protocols. Similarly, check whether the URL contains a valid file_info.
Task
Write the conditions to return a Boolean value of True if the URL is valid, and False if either the Protocol or the File extension is not valid.
main.py х +
1 def validate_url(url):
2 *****Validates the given url passed as string.

4 Arguments:
5 url --- String, A valid url should be of form :///

7 Protocol = [http, https, ftp]
8 Hostname = string
9 Fileinfo = [.html, .csv, .docx]

25

Answer:

25 35

Explanation:

First if checks if num is greater than 25, it is so it prints 25 with a space after and adds 10 to num (num is now 35)

Then it checks if num is greater than 30, it is, so it prints 35 with a space after and adds 5 to num (num is now 40)

Lastly, it checks if num is greater than 45, it is not, so the program terminates with output: "25 35 " (note the space at the end)

The advantage of caching an entire line in the main memory instead of a single byte or word at a time is to avoid cache pollution from used data

Explanation:

The major advantage of caching an entire line instead of single byte is to reduce the excess cache from used data and also to take advantage of the principle of spatial locality.

Explanation:

Answer:

Explanation:

The following code is written in Java, it prompts the user to enter 10 integers and saves them to an ArrayList. Then it prompts for 5 strings and saves them to another ArrayList. Then, it calls the sort method and adds the lists as parameters. Finally, it prints out both lists completely sorted in ascending order.

import java.util.ArrayList;

import java.util.Scanner;

class Division{

   public static double division(double a, double b) throws Exception {

       if(b == 0)

           //throw new Exception("Invalid number.");

           return (a / b);

       return a / b;

   }

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       ArrayList<Integer> mylist2 = new ArrayList<>();

       for (int x = 0; x < 10; x++) {

           System.out.println("Please Enter a Number: ");

           int number = in.nextInt();

           mylist2.add(number);

       }

       ArrayList<String> mylist = new ArrayList<>();

       for (int x = 0; x < 5; x++) {

           System.out.println("Please Enter a Word: ");

           String word = in.nextLine();

           mylist.add(word);

       }

       sort(mylist);

       sort(mylist2);

       for (String x: mylist) {

           System.out.print(x + ", ");

       }

       System.out.println("");

       for (int x: mylist2) {

           System.out.print(x + ", ");

       }

   }

   public static <E extends Comparable<E>> ArrayList<E> sort(ArrayList<E> list) {

       E temp;

       if (list.size()>1) // check if the number of orders is larger than 1

       {

           for (int x=0; x<list.size(); x++) // bubble sort outer loop

           {

               for (int i=0; i < list.size() - x - 1; i++) {

                   if (list.get(i).compareTo(list.get(i+1)) > 0)

                   {

                       temp = list.get(i);

                       list.set(i,list.get(i+1) );

                       list.set(i+1, temp);

                   }

               }

           }

       }

       return list;

Answer:

responsiveness and intuitive

Explanation:

The two main purposes of a good web page design is responsiveness and intuitive. A webpage needs to be designed in such a way that the individual using it can easily find what they are looking for and understand what each function in the webpage does without having to ask for help or go through an extensive tutorial. They need to be able to use the website for the first time and immediately be able to use it as if they have used it countless times before. The webpage also needs to be designed with responsiveness in mind. So much so that the webpage runs fluently, loads images fast, and scales to the size of the monitor correctly. As a rule the webpage should not take longer than 2 seconds to load.

D. Requirement Assessment.

Explanation:

The requirement assessment is carried out during the initial development stage to meet the user's requirements.  This assessment does not necessarily deal with application security.  However, the other three aspects are security-related.  They focus on the areas where application security is mostly required to reduce errors and technical weaknesses of a software, including authentication, privacy, access control, data segregation, and error handling.

Explanation:

I just took the test and passed when you have multiple choice questions always pick ones that similar to each other and make sure it fit the question.

Answer:

The program is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 String score;

 System.out.print("Scores: ");

 score = input.nextLine();

 String[] scores_string = score.split(" ");

 double total = 0;

 for(int i = 0; i<scores_string.length;i++){

     total+= Double.parseDouble(scores_string[i]);  }

 double average = total/scores_string.length;

 System.out.format("Average: %.3f", average); }

}

Explanation:

This declares score as string

 String score;

This prompts the user for scores

 System.out.print("Scores: ");

This gets the input from the user

 score = input.nextLine();

This splits the scores into an array

 String[] scores_string = score.split(" ");

This initializes total to 0

 double total = 0;

This iterates through the scores

 for(int i = 0; i<scores_string.length;i++){

This calculates the sum by first converting each entry to double

     total+= Double.parseDouble(scores_string[i]);  }

The average is calculated here

 double average = total/scores_string.length;

This prints the average

 System.out.format("Average: %.3f", average); }

}

Answer:

study-time survey, project schedule, prioritize tasks, reward system.

Explanation:

Time management can be defined as a strategic process which typically involves organizing, planning and controlling the time spent on an activity, so as to effectively and efficiently enhance productivity. Thus, when time is properly managed, it avails us the opportunity to work smartly rather than tediously (hardly) and as such making it possible to achieve quite a lot within a short timeframe. Also, a good time management helps us to deal with work-related pressures and tight schedules through the process of properly allocating the right time to the right activity.

Hence, time-management techniques work most effectively when performed in the following sequential order; study-time survey, project schedule, prioritize tasks, and designing (creating) a reward system.

Answer:

The Answer is:
D. study-time survey, project schedule, prioritize tasks, reward system

Explanation:

got it right on edge

Answer:

Following are the code to the given question:

public class Main//defining a class Main

{

static int permut(int n, int r)//defining a method permut that holds two variable

{

return fact(n)/fact(n-r);//use return keyword to return calcuate value

}

static int fact(int n)//defining a fact method as recursive to calculate factorials

{

return n==0?1:n*fact(n-1);//calling the method recursively

}

public static void main(String[] abs)//main function

{

//int n=7,r=4;//defining integer variable

System.out.println(permut(7,4));//use print method to call permut method and print its values

}

}

Output:

840
