(Directi coding round question)How to implement the given requirement?

Implement an in memory key value datastore server with the following features:
The program should create a socket which listens on port 60## (where ## is your user number). A
client program NEED NOT be written to connect to the socket. telnet can be used. Once connected to
your program it should support the setting and retreival of keys:
set
get
Eg:
set hello world
get hello
Output: world
keys
“Printing list of keys”

  1. hello

Objective 2

Create a second instance of the same program running on a different port
Write a client that is capable of taking input values from a file / telnet
Your client must be able to intelligently shard data across the two instances of your program via
sockets
Eg:
“Start two instances of your server – A and B”
SET raghu 21 # Data goes to server A
SET bharath 23 # Data goes to server B
SET ayush 22 # Data goes to server A
SET kalyan 24 # Data goes to server B

Bonus Question:

If there is a ttl value set for the key, it should be deleted from the memory once ttl is expired.
set
Eg:
set hello world 60
In the above case the key hello should be deleted, 60 seconds after it has been set.
Hints for C/C programmers
Common function calls you will need
socket (Refer man 2 socket )
listen (Refer man 2 listen )
bind (Refer man 2 bind )
Feel free to use C STL library to make your coding.

please provide the detailed explanation to the problem and also the solution.
