Submit a java file. Write a program where you input 4 numbers and the output generates the average of the 4 numbers. The output may not be negative and <= 100. If any value is negative or >100, it should be replaced by the value of 30. For all such values, you will replace them with a value of 10. The program should produce the following output:

Today's average amount is: $xx.xx.

(b). How long would it take to send two back-to-back 300-byte packets from A to B?

(c). How long would it take to send three back-to-back 200-byte packets from A to B?

Your network employs basic authentication that centers on usernames and passwords. However, you have two ongoing problems. The first is that usernames and passwords are frequently lost by negligent users. In addition, adversaries have, on occasion, fooled employees into giving up their authentication information via social engineering attacks. Discuss at least two things could you do to strengthen the use of basic username and password authentication, as discussed in the course textbook.

Your answer should be approximately 200-250 words in length.

It have to be your own words and no outside sources.

I am confused with Python I have to write a specification for an email address. In one string a valid email address and the other without a valid email address.

Ex:

print(text_match("My teacher’s email is [email protected]"))

print(text_match("My teacher has no email address"))

Please write simple python program with explanation

Problem statement:

Stock markets are venues where buyers and sellers of shares meet and decide on a price to trade.Eddard is very interested in trading in stock market and he started gathering information of one stock.He has projected market prices for that share over the next n months.Eddard wants to purchase and resell the share to earn profits.He is much worried about the loss that might occur so he wanted to calculate "Minimum loss" according to following rules :

1.The share cannot be sold at a price greater than or equal to the price it was purchased at(i.e. it must be resold at a loss).

2.The share cannot be resold within the same month it was purchased.

Find and print the minimum amount of money Eddard must lose if he buys the share and resells it within the next n months.

Input Format:

The first line contains an integer n,denoting the number of months of share data.

The second line contains n space separated long integers describing the respective values of p1,p2,...pn.

Constraints:

1<=n<=10^5

1<=pi<=10^16

All the market prices are distinct and valid answer exists.

Output Format:

Print a single integer denoting the minimum amount of money Eddard must lose if he buys the share and resells it within the next n months.

Sample Input1:

3

5 10 3

Sample Output1:

2

Explanation:

Eddard buys the stock in month1 at price p1=5 and sells it in month 3 at p3 for a minimal loss of 5-3 = 2 .

Sample Output2:

5

77 82 76 88 80

Sample Output2:

1

• Adapt the original LinkList class to use the generic Gnode class

Code for LinkList below

class LinkList {
    Node llist;

    LinkList( int sz ) {
   if ( sz <= 0 ) {
       llist = null;
   }
   else {
       // start with list of size 1
       llist = new Node( "0", null ); 
       Node current = llist; // temp node for loop
       // add further nodes
       for ( int i=1; i<sz; ++i ) {
      // create node and attach it to the list
      Node node2Add = new Node( Integer.toString(i), null );
      current.setNext(node2Add);   // add first node
      current=node2Add;
       }
   }
    }
    
    /**
     * Print all the elements of the list assuming that they are Strings
     */
    public void print() {
   /* Print the list */
   Node current = llist; // point to the first node
   while (current != null) {
       System.out.print((String)current.getElement() + " ");  
       current = current.getNext(); // move to the next
   }
   System.out.println();  
    }

    public void deleteFirst() {
   if ( llist != null ) {
       llist = llist.getNext();
   }
    }

    public void deleteLast() {
   if ( llist == null ) return; // no node
   Node prev = llist;
   Node current = prev.getNext(); 
   if ( current == null ) { // only 1 node
       llist = null;
       return;
   }
   while ( current.getNext() != null ) { // more than 1 node
       prev = current;
       current = current.getNext();
   }
   prev.setNext( null );
   return;
    }

    // create and display a linked list
    public static void main(String [] args){
   /* Create the list */
   LinkList llist = new LinkList( 5 );
   /* Print the list */
   llist.print();
   /* delete first and print */
   llist.deleteFirst();
   llist.print();
   /* delete last and print 5 times */
   for ( int i=0; i< 5; ++i ) {
       llist.deleteLast();
       llist.print();
   }
    }
}

Code for GNODE below

public class GNode<E> {
  // Instance variables:
  private E element;
  private GNode<E> next;
  /** Creates a node with null references to its element and next node. */
  public GNode() {
    this(null, null);
  }
  /** Creates a node with the given element and next node. */
  public GNode(E e, GNode<E> n) {
    element = e;
    next = n;
  }
  // Accessor methods:
  public E getElement() {
    return element; 
  }
  public GNode<E> getNext() { 
    return next;
  }
  // Modifier methods:
  public void setElement(E newElem) { 
    element = newElem; 
  }
  public void setNext(GNode<E> newNext) {
    next = newNext; 
  }
}

XML

1) Create an XML schema for a catalog of cars, where each car has the child elements make, model, year, color, engine, number_of_doors, transmission_type, and accessories. The engine element has the child elements number_of_cylinders and fuel_system (carbureted or fuel injected). The accessories element has the attributes radio, air_conditioning, power_windows, power_steering, and power_brakes, each of which is required and has the possible values yes and no.

2) Create an XML document with at least three instances of the car element defined in the XML schema of previous exercise. Process this document by using the previous XML schema, and produce a display of the raw XML document. Create a CSS style sheet for the XML document and use it to override the default styles of the XML document.

-Using MySQL Workbench Data Modeler, create three (3) models from the tables below. Show Table 1 in 3rd Normal Form. Show Table 2 in 3rd Normal Form. Merge the 3rd Normal Forms of Table 1 and Table 2 into a single 3rd Normal Form model. Note that you only can model table and column names and data types. The data shown is for your reference to determine functional, partial, and transitive dependencies.
-Provide a summary of the steps you took to achieve 3rd Normal form. Include your rationale for new table creation, key selection and grouping of attributes.

- Write a function with a parameter called A (which is between 1 and 10) and prints the multiplication table for 1 to A. • Note: Do not need to draw the horizontal and vertical lines. • Example for A = 10.

In Python write a program that prompts the user for a file name, make sure the file exists and if it does reads through the file, count the number of times each word appears and then output the word count in a sorted order from high to low.

The program should:

• Display a message stating its goal
• Prompt the user to enter a file name
• Check that the file can be opened and if not ask the user to try again (hint: use the try/except structure)
• Count the number of times each word appears in the file, regardless if in lowercase or uppercase (hint: use dictionaries and the lower() function)
• Display the word count in order from high to low
• If a few words have the same count, sort the display in an alphabetic order
• For example, for the attached file NYT2.txt, the top five words in the output should be

the - 7

in - 6

to - 5

and - 4

of - 4

Remember:

• DO NOT use more advanced functions than needed.
• Make sure to include comments that explain all your steps (starts with #).
• Run the program a few times to make sure it executes and meets all the requirements.

Create a BMI calculator that reads the user’s weight and height (providing an option for the user to select which formula to use), and then calculates and displays the user’s body mass index. Also, display the BMI categories and their values from the National Heart Lung and Blood Institute: http://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm (Links to an external site.) so the user can evaluate his/her BMI.
