Answer:
By Using the Greedy- Activity- Selection algorithm
Explanation:
The Greedy- Activity- Selection algorithm in this case involves
First finding a maximum size set S1, of compatible activities from S for the first lecture hall.
Then using it again to find a maximum size set S2 of compatible activities from S - S1 for the second hall.
This is repeated till all the activities are assigned.
It requires θ(n2) time in its worse .

This is a model of working memory, which can be otherwise called here and now memory in lay man's term, that tries to clarify how the mind forms related thoughts, particularly semantic or verbal ideas. The spreading enactment show is one way intellectual clinicians clarify the preparing impact, which is the noticeable wonder that a man can all the more rapidly review data about a subject once a related idea has been presented.
