After the online assessment, there are 5 interviews, each with 4 questions, and 1 behavioral question.

Each interview is 1 hour long. The behavioral question is 45 minutes.

This process will take nearly a full day, step by step.

Here's the text to clean up: [('John', 5), ('Mary', 4), ('Sherry', 10), ('John', 3), ('Mary', 3), ...]

There are duplicate names in this list, and each name corresponds to the number of characters in their text messages. Given such a list and a specific number N, you are asked to return the top N most active users.

I used a dictionary to count how many characters each person sent. Then it was sorted.
