Give some hint for optional question last two questions of assignment 3

How to find common location names of two different data frames.

For Optional 1:

We need to merge the datasets according to the Location to get common locations and then we can get the length of dataframe

For Optional 2:

First We need to get the dataset for the countries which have more than 10 million population.
Then we need to get the top 20 data for lowest GDP and lowest number of beds (this is the same as previous question which asks for highest number of cases/deaths/tests)
Now As similar to Previous optional question we need to merge these two datasets to get the common countries and get the length of the dataset.

Hope the hints are enough…because I didn;t really told anything related to answer…
