Queue

Another important DS we are going to discuss

QUEUE …

What is queue

See the above Image ,  peoples are standing in the queue and guy in the counter giving tickets or serving something …

Now think , if counter guy able to give ticket  in an ignore time , then do we require queue anymore … No absolutely not .

 But in practical situation, service provider(counter guy) not able to  serve the request (ppl standing in the queue) in an ignore time. So, we need queue in order to serve all the request.

 Queue has a sequence of the request, where which request comes first that will be processed first. And of-course there are some priority queue (this we will discuss later )

Lets see the implementation of the queue (java)   .. it is under construction .. I'll post this soon
