2.How does Prolog try to resolve our Queries?
a.The programmer specifies the algorithmic approach, performance is all in the hands of how clever the programmer writes their algorithms.
b.The language applies some AI to our query and precludes obviously false information.
c.Row by agonizing row. There is nothing particularly clever about the solve, it just brute forces its way through the data looking for resolutions.

Write an IterativeMergeSort function given these parameters and following the prompt
IterativeMergeSort(vector<int> v, int low, int high)
IterativeMergeSort
In-place sorting refers to sorting that does not require extra memory arrays. For
example, QuickSort performs partitioning operations by repeating a swapping operation on two
data items in a given array. This does not require an extra array.
We can improve the performance of MergeSort by utilizing a non-recursive method and
using only one additional array (instead of one array on each recursive call). In this improved
version of MergeSort,
IterativeMergeSort
, one would merge data from the original array into
the additional array and
alternatively
copy back and forth between the original and the
additional temporary array.
Please re-read the last sentence as it is critical to the grading of
the lab.
For the IterativeMergeSort we still need to allow data items to be copied between the
original and this additional array as many times as O(
log
n). However, given the iterative nature
we are not building up state on the stack.

Rental Shop
A. Create an abstract class named SummerSportRental that is to be
used with for a summer sports rental
shop. The SummerSportRental class must have the properties of
newModel which takes on the type
boolean, and rentalCost which takes on the type double, and
rentalNumber which is an identification
number as an long integer.These member variables must all be
private!
It also must include the following member functions:
1. equals() which returns true if two SummerSportRental objects
have the same rentalNumber.
2. all of the appropriate get/set methods for each of the above
member variables. Make sure to have
data validation done on the set methods to prevent invalid/illegal
values from being passed into the
member variables. (Example: rentalCost should not be allowed to be
negative).
3. include an abstract method named lateCharge, that will only be
implemented in child classes that
inherit the SummerSportRental class.
B. Create three children classes that inherit the SummerSportRental
class, named WaterSkiRental,
PaddleboardRental, and BeachCruiserBikeRental.
The WaterSkiRental class should have one private member variable
named size as an integer that will be
used to store the size of the water ski in centimeters. Implement
the get/set method for this member
variable. The abstract method in the SummerSportRental class, named
lateCharge must be implemented to
charge a late charge of 10% of the rental cost. Be sure to include
a method named toString to output the
data stored in the member variables for this class. No main method
in the class allowed!
The PaddleboardRental class should have two private member variable
named size as an integer that will
be used to store the size of the paddle board in centimeters, and
another member variable named style as
an enumerated type with the values (SINGLE, DOUBLE to denote if the
paddle board is a single person
board or a two person board). Implement the get/set methods for
these member variables. The abstract
method in the SummerSportRental class, named lateCharge must be
implemented to charge a late charge
of 20% of the rental cost. Be sure to include a method named
toString to output the data stored in the
member variables for this class. No main method in the class
allowed!
The BeachCruiserBikeRental class should have two private member
variable named wheel_szie as an
integer that will be used for storing the wheel size in centimeters
of the beach cruiser bike, and another
member variable named capacity as an enumerated type with the
values (SINGLE, DOUBLE, TRIPLE
[which has a very stylin' side cart to it]) that stores the seating
capacity of the beach cruiser bike. Implement
the get/set methods for these member variables. The abstract method
in the SnowSportRental class, named
lateCharge must be implemented to charge a late charge of
(20+capacity*5)% (late charge for single=25%,
double=30%, triple=35%) of the rental cost. Be sure to include a
method named toString to output the data
stored in the member variables for this class. No main method in
the class allowed!
C. Create separate test class source files with their respective
main methods to test each implemented
method in the WaterSkiRental, PaddleboardRental, and
BeachCruiserBikeRental classes. The list below is
the minimums for the test cases for each of the child
classes:
WaterSkiRental:
1. equals() method
2. newModel ( test get and set )
3. rentalCost ( test get and set )
4. rentalNumber ( test get and set )
5. size ( test get and set )
6. lateCharge - make sure it adheres to the specifications
above.
7. toString ( test toString method )
A total of 11 tests for WaterSkiRental class ( tests 1-4 are
actually for the SummerSportRental class, and will
not need to be repeated for PaddleboardRental and
BeachCruiserBikeRental class test )
PaddleboardRental:
1. size ( test get and set )
2. style ( test get and set )
3. lateCharge - make sure it adheres to the specifications
above.
4. toString ( test toString method )
A total of four tests for PaddleboardRental class
BeachCruiserBikeRental:
1. wheel_size ( test get and set )
2. capacity ( test get and set )
3. lateCharge - make sure it adheres to the specifications
above.
4. toString ( test toString method )
A total of four tests for BeachCruiserBikeRental class

Create an application named ShirtDemo that declares several Shirt objects and includes a display method to which you can pass different numbers of Shirt objects in successive method calls.
The Shirt class contains auto-implemented properties for a Material, Color, and Size (all of type string).

//Program.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ShirtApplication

//Create an instance of Shirt
Shirt shirt = new Shirt("cotton", "white", "L");
//print heading
Console.WriteLine("{0,-12}{1,10}{2,10}", "Material", "Color","Size");
//call display method
display(shirt);
//Create an instance of Shirt
shirt = new Shirt("cotton", "blue", "XL");
//call display method
display(shirt);
//Create an instance of Shirt
shirt = new Shirt("polyester", "pink", "M");
//call display method

display(shirt);
Console.ReadKey();
}
//The metod display that takes Shirt object and prints the properties of shirt object

This is a java assignment inspired by Caesar algorithm with some minor modifications. You are required to take in three inputs; a string, which is the message that you want to encrypt, an integer number that we call it salt, which is going to salt your plain message to help create a better encrypted message and an int to be used for displacement of the letters.
Your algorithm is going to encode the message letter by letter. If the position of the letter in your message is odd, then it should add the value of this letter to the displacement value plus salt. If the letter is in even position, then it should be added to the displacement subtracted from salt. For example, assume displacement = 3 and salt = 5, then letter ‘A’ will be replaced by ‘I’, if it is in odd position and by ‘C’ if it is in even position.
The message that you read can contain any character that is typeable (i.e. you can see the typable characters on your keyboard). Your program finally should output the encrypted message.
Sample input and corresponding output:

Build a class called “Animal” which has three attributes: “ArrayList<String> diet”, “int numOfLegs”, and “Boolean carnivore”. Build a constructor with three parameters to set the three attributes. In the constructor, if the number of legs given in the parameter is below 0 set the number of legs equal to 0. Add seven methods:
Now that we have a base class, we’re going to make a subclass of our “Animal” class. Make a class called “Cat” that is a subclass of “Animal”. In “Cat” add a new attribute “String color”. Build a constructor with two parameters, an arrayList<String> diet and String color, in the new constructor call the superClass’s constructor and assume the number of legs of all cats is 4 and every cat is a carnivore. Add a method “String getColor()” that returns the cat’s color. Replace (override) the original “makeSound()” method with a new “makeSound()” function that returns the string “Meow”.
