Task $1$: UDP Socket Programming

Objective:

Create a client$-$server application using UDP sockets in Python where the client sends a sentence to the server, and the server returns the sentence with the order of words reversed.

Requirements:

UDP Client:

$$ Create a UDP socket.

$$ Get a sentence as input from the user.

$$ Send the sentence to the server.

$$ Receive the reversed sentence from the server and print it$.$

UDP Server:

$$ Create a UDP socket and bind it to a specific IP and port.

$$ Wait for a message from the client.

$$ Upon receiving a sentence, reverse the order of words in the sentence.

$$ Send the reversed sentence back to the client.
