Question: Find the visitor who spent the most amount of time at the White House?

My answer: Alan C. Prather

First, please tell me whether my answer is correct?

Second, I’d like to know if there’s better approach to arrive at the answer?

My approach:
Step 1 - I created a dictionary with unique visitor names as keys and their cumulative meeting durations as values.

Step 2 - I reversed the keys and values to create another dictionary so that I can use the max function to find out the maximum cumulative duration of meetings and the corresponding visitor, which would be our answer.

#2

Your answer does look to be correct as per my own solution.

You don’t need to reverse the keys and values to get the answer. Google something like:

python dictionary max value key

and see what results you get that could simplify your 2nd step.
