Given a linked list of N nodes. The task is to reverse the list by changing links between nodes (i.e if the list is 1->2->3->4 then it becomes 1<-2<-3<-4) and return the head of the modified list.

Input

User Task:

Since this will be a functional problem, you don't have to take input. You just have to complete the function ReverseLinkedList that takes head node as parameter.

Constraints:

1 <=N <= 1000

1 <= Node.data<= 100

Output

Return the head of the modified linked list.

Given a singly linked list and an element K, your task is to insert the element at the tail of the linked list.

Input

User Task:

Since this will be a functional problem, you don't have to take input. You just have to complete the function addElement() that takes head node and the integer K as a parameter.

Constraints:

1 <=N<= 1000

1 <=K, value<= 1000

Output

Return the head of the modified linked list

You probably are fond of games. This quiz though is not that complicated. You are simply going to work with a point on a screen, and a circle on a screen as well. And let's consider them as the characters in the game. We are going to call both of these characters as Movable objects. Objects are said to be Movable if they can be moved around the screen. The following simple movements are allowed:

public void moveLeft(); // moves the x to the left by 1 unit

public void moveRight(); // moves the x to the right by 1 unit

public void moveUp(); // moves the y 1 unit upward

public void moveDown(); // moves the y 1 unit downward

public void display(); // prints all the info about

Instructions

∙ Name your Java package as: “com.lastname.duka”.

∙ Name your database using your names as: “db_first_last_studentNumber”. ∙ Name all your tables in your database using this format: “tbl_tableName”. ∙ Add a copyright message (tiny text) on all your GUIs. 

Milestone:

For this unit, you are required to develop a GUI application using Java. The application should connect to a database and should be able to perform any CRUD operation.

Main goal: 

Develop a Java application with GUI for a primary school called Duka.

Functional Requirements:

The application should allow: 

i. A shop attendant to be able to login to upload stock of items (with prices). ii. A buyer be able to search for items, get their prices and make an order.

Non-functional Requirements:

The application should:

i. Have a user-friendly GUI for both shop attendant and buyer.

ii. Not crash in case a user makes a mistake, instead it should provide a clarification/warning.

Design a web page using HTML and CSS for a Music store. Add suitable background image.

You have to generate electricity bill for a customer with the details as give below: Customer ID, Customer Name, Customer Address, Contact No, Units Consumed, Total payable amount. Following are the norms to calculate the unit amount:

a) for initial 100 units it will cost 6 rupees per unit

b) for next 100 units it will cost 8 rupees per unit

c) for next all units it will cost 10 rupees per unit

Hint:-

-get user input of customer name, id, address, contact no, units consumed

-give output as customer details and total payable amount but the payable amount wil be based on the unit consumed (if the total unit 300 it will be like 100*6= 600 as per first 100 units and 100*8= 800 as per second 100 units rest 100*10= 1000. so total will be 600+800+1000=2400).

Write a program in Java, define a STUDENT class with Roll No, Name and Marks of 3 subjects. Define one function to find the best two subject marks for student.
