Answer 1

What's with the tags? Instead of tagging people, how about mentioning the important things? Such as "what programming language are you using", and "how is the data stored"?
Oh, and don't expect other people to write the code for you... That's not what SOLOLearn is for.... (emphasis on the SOLO ;) ).
