Query about ZIO?

Can anyone tell what ZIO is really mean that we have to write algorithm for questions or program?

Have a look at the past papers once.
It’s no use asking without doing some research of your own…

Hi,

In ZIO you need to just provide the final answer after solving the question for the specific cases.
