Answer 1

To showcase the difference in popularity rank between the current year and the previous year of each company using vectorized operations in Python, utilize the pandas library to efficiently manipulate the data.

Step-by-step explanation:

To showcase the difference in popularity rank between the current year and the previous year of each company using vectorized operations in Python, you can use pandas, a popular data manipulation library. First, read the data into a pandas DataFrame. Then, create a new column to store the difference in popularity rank between the two years by subtracting the rank of the previous year from the rank of the current year. Finally, use vectorized operations to efficiently calculate and update the new column with the rank differences.
