Part I (85%): Write a client program and a server program to implement the following protocol on top of UDP. Client Program: 1. Display a message to ask the User to input the DNS or IP of the machine on which the Server Program runs. 2. Display the following table on the standard output: Item ID Item Description 00001 New Inspiron 15 00002 New Inspiron 17 00003 New Inspiron 15R 00004 New Inspiron 15z Ultrabook 00005 XPS 14 Ultrabook 00006 New XPS 12 Ultrabook XPS 3. Display a message on the standard output to ask the User to input an Item ID, and validate the user input. If the input is not a valid Item ID, ask the User to re-type it. 4. Once getting a valid item ID from the User, send a request including this Item ID (e.g., 00005 or "00005") to the Server program to ask for a quote, and record the local time right before sending such request. 5. Receive and interpret the response from the Server program, get the local time right after such response is received, and display the following information on the standard output, (e.g., if 00005 were provided by the User earlier on) Item ID Item Description Unit Price Inventory RTT of Query 00005 XPS 14 Ultrabook $999.99 261 where "RTT of Query" is the difference between the time in Steps 5 and 4 in millisecond. 6. Display a message on the standard output to ask the User whether to continue. If yes, repeat steps 2 through 5. Otherwise, close the socket and terminate the Client program. Server Program: 1. Maintain the following information using an appropriate data structure of your choice (i.e., an array of a Class you defined). You do not have to place it in a file although you certainly can if you like. Item ID Item Description Unit Price Inventory 00001 New Inspiron 15 $379.99 157 00002 New Inspiron 17 $449.99 128 00003 New Inspiron 15R $549.99 202 00004 New Inspiron 15z Ultrabook $749.99 315 XPS 14 Ultrabook $999.99 261 00006 New XPS 12 Ultrabook XPS $1199.99 178 2. Wait for receiving a packet from a Client 3. Once a packet is received from a Client, retrieve the information relevant to the requested Item ID from the data structure you used in Step 1 and send back such information to the client. 4. Repeat Steps 2 and 3 infinitely until an exception is caught. 5. Close the datagram socket. ...ms 00005
