Example 2 :

Patients are treated in a single ward by the doctors assigned to them. Usually each patient will be assigned a single doctor, but in rare cases they will have two.

Heath care assistants also attend to the patients, a number of these are associated with each ward. 

Initially the system will be concerned solely with drug treatment. Each patient is required to take a variety of drugs a certain number of times per day and for varying lengths of time.

The system must record details concerning patient treatment and staff payment. Some staff are paid part time and doctors and care assistants work varying amounts of overtime at varying rates (subject to grade).

The system will also need to track what treatments are required for which patients and when and it should be capable of calculating the cost of treatment per week for each patient (though it is currently unclear to what use this information will be put).

Introduction

This help page shows you how to install Microsoft's Internet Information Services (IIS) 5.1 web server for Windows XP Professional.

Can it be installed on Windows XP Home Edition?

No.

Why do I need to do this?

Contract Eagle is a browser-based software product which requires Microsoft's web server platform to run. All other systems supported by Contract Eagle (eg. Windows Server 2003, Windows Vista, Windows 7, WIndows Server 2008) allow IIS to be installed automatically. Windows XP Professional does not support this facility and therefore you need to follow these manual steps to complete the installation.

Lets Get Started

IIS isn't installed by default on a standard installation of Windows XP Professional. If you are not sure then it is most likely that it isn't already installed.

You will need your Windows XP Professional CD with you and you will need to be able to log in as an administrator on your computer.

Step 1 - Control Panel

Go to Control Panel -> Add Remove Programs 

Step 2 - Windows Configuration

Click Add/Remove Windows Components

Step 3 - Select IIS

 The Windows Component Wizard will appear. You need to select the Internet Information Services (IIS) checkbox and then click Next.

Step 4 - Insert Your XP Professional CD

Now you will probably be asked to insert your Windows XP Professional CD.

Do not be concerned if you do not see this step. It means your system has probably been installed via the network, meaning you don't have to locate and insert your CD.

Step 5 - Installing

Once your WIndows XP Professional CD (or network based installation) is available you will see a window like the following, indicating that Internet Information Services is being installed.

Step 6 - Finished

When installation has finished you will see the following window, which shows that you have successfully installed Microsoft Internet Information Services 5.1.

Step 7 - Configure ASP.NET

This step registers Microsofts "DOT NET" technology within the IIS Web Server.

You may achieve this by clicking the "Configure ASP .NET" button within the Contract Eagle Installation Assistant. (Technical Note: This executes "aspnet_regiis -i" for .Net v2.0) 

Congratulations!

IIS has now been installed and the Contract Eagle setup assistant will be able to complete its installation for you.

After finding a lot in books and Internet I found this easy method on how to create B.Tree from studying following data

a)  - INORDER Traversal 

-POSTORDER Traversal 

OR 

b)  -INORDER Traversal 

-PREORDER Traversal 

We usually get Questions like :-

Create Binery tree from following tree Traversals

1)  Inorder:   E  A  C  K  F  H  D  B  G

    Preorder:  F  A  E  K  C  D  H  G  B

2)   INORDER:      D J H B E A F I C G 

      POSTORDER: J H D E B I F G C A

  

HERE the most important think to ALWAYS remember is :-

• In PREorder  FIRST element is ROOT of the tree
• In POSTorder  LAST element is ROOT of the tree

I hope you got it :P

i.e considering 1) Question

1)  Inorder:   E  A  C  K  F  H  D  B  G

    Preorder:  F  A  E  K  C  D  H  G  B

Considering 2) Question

2)   INORDER:      D  J  H  B  E  A  F  I  C  G 

      POSTORDER: J  H  D  E  B  I  F  G  C  A

* BLACK highlighted letters are roots 

** RED highlighted letters will go to LEFT SUB TREE  of Root 

***GREEN highlighted letters will go to RIGHT SUB TREE of Root

Let us Start with Question 1)

Step 1)

Now as we know which one is Root So...

                                   F

                                /     \

             ( E A C K)           (H D B G) 

Step 2)

Now FOR LEFT SUB TREE we have 

E A C K from Inorder and same letters from Preorder A  E  K  C 

i.e  Inorder   E A C K 

      Preorder A  E  K  C 

now have found Root again so now tree is 

                                   F

                                /     \

                             A       (H D B G) 

                           /    \

                         E     ( C K )

Step 3)

 Now letters are

Inorder    C  K

Preorder  K C

So now tree is 

                                   F

                                /     \

                             A       (H D B G) 

                           /    \

                         E     K

                               /

                             C

Same procedure can be done on Right Sub tree Of root F

For Postorder we have to find Root as the last element in traversal....
