Feature #1: Add Likes
Explore how to build an API module for Twitter that sums likes on tweets represented as strings. Learn digit-by-digit addition without converting strings to integers, maintaining string format and managing carry-over. Understand the time and space complexity of this approach and consider extending it to binary numbers.
We'll cover the following...

For this purpose, our team member has already extracted the data and stored it in a simple text file for us.
