Let if I develop an elevator (lift) system.
So which data structure we should be followed to build the system.

What I have tried:

I have googled but not get as well.

An impossible question to answer. You create, or use existing, data structures, based on the requirements of your application.

I have just asked as scenario. I have given an interview.
I have suggested one of data structure to interviewer. But might be not worthy. So if anyone answer this or any link it's would be helpful.

There is no way to answer this question. What you should have been doing is asking the interviewer questions about the system and you build your data structure from that.

Like I said, it is impossible to answer. The only information you have provided is that this is an elevator system. But that tells us nothing about the requirements of the system, so there is no way to give a valid response.

"I have suggested one of data structure to interviewer."

But, you don't tell us what that is.

ok, suggest me that one.

unfortunately, I am not a jaadoogar who can use mantras to summon up what you have not done for yourself :) You do research, You plan for code implementation, You write a spec, You post specific questions here based on your evolving code.

You seem to believe that we can magically create a full project specification from the most vague information. No one, as I have already said twice, can possibly guess what you even mean by, “data structure for an elevator system”. You are starting half way through the design phase of the project, so you may not need any data structure.

If you want to simulate an elevator, it will be a state machine that reacts to inputs (buttons, sensors) and controls outputs (motor, doors, display). A state machine isn't usually considered a data structure, however, because it will use various data structures (e.g. a queue of messages) in its implementation.

There is no magic "standard data structure" that will automatically fit your lift system.
The trick is that just like with the vast majority of problems, you have to create/craft your own solution.
Remember that a data structure is never a solution to a problem, it is the combination of data structure and associated code/program that is a solution to the problem.

The general approach is to list all requirements in order of decreasing importance.
then create a data structure that fit the first requirement, and refine the data structure as you include other requirements.
You will see that as you define the data structure, you also plan how you will use it.

There isnt an easy answer, but you may collect all data which you may need and get. Important is than to define all use cases like up or down rides and some emergency cases like overload or fire alarm. Think also about some graphical presentation like payload, state and position. This conceptional phase should be some hours and best is to use paper or UML and present your results to somebody who understands it. So you may find some flaws in your concept.

Best practice is to use some classes and enums and also use database for saving and loading the data. Some replay would be the creme on the top.
