Solve the following problem by showing the design of your solution as an algorithm.

The problem – The program will take two integers from the user, say n1 and n2. It will then print the sum of all numbers between n1 and n2, inclusive. For example, if the user enters 5 and 9, the program will print the value of 5+6+7+8+9. On the other hand, if the user enters 5 and -2, the program will print the value of 5+4+3+2+1+0+(-1)+(-2). Note: Do not assume the user will always enter the smaller number first.

Develop a Python application that will accept two non-negative integers and store them in a list and will append ten additional values equivalent to the sum of the two previous elements of the list.

Sample Output:

First Number: 1

Second Number: 3

[1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322]

Create a class called Scholarship which has a function Public void Merit() that takes marks and fees as an input. Merit method should get an marks as input using params

If the given mark is >= 70 and <=80, then calculate scholarship amount as 20% of the fees

If the given mark is > 80 and <=90, then calculate scholarship amount as 30% of the fees

If the given mark is >90, then calculate scholarship amount as 50% of the fees.

In all the cases return the Scholarship amount

Example:

Base integer = 3

Initial factor = 2

Number of times to process = 3

Process:

1.) 2 x 3 = 6

2.) 6 x 3 = 18

3.) 18 x 3 = 54

Therefore, the output would above would be 54.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for the 3 integer inputs required for this program and calls the getResult().
2. This getResult() function has the following details:
3. Return type - int
4. Name - getResult
5. Parameters
6. int - Base integer
7. int - Initial factor
8. int - Number of times to process
9. Description - this is a recursive function which implements the desired behavior explained in the problem description
10. The getResult() function is partially implemented already. Your only task is to add the correct recursive case.

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has the following description:
3. Return type - void
4. Name - preserveString
5. Parameters
6. The string
7. Length of the string
8. Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left.
9. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

Write a complete Java program illustrating the difference between instance and static members of class. Indicate with comments where each is used and explain the significance of making the instance or static. (6 marks)

Making use of object orientation write a program that stores and evaluates the total cost for items bought from a supermarket. The cashier should enter the following: - Product code, Price and Quantity. The total price should be evaluated as follows: -

Total cost = Price * Quantity

If the total cost per item is more than 20,000 there is a discount of 14% on that item and a discount of 10% on an item whose total cost is between 10,000 and 20,000. No discount is given on items whose total cost is less than 10,000
