Counting subcategories in an online store

About the exercise

Think of Amazon: they have a few of main categories, but every time you land on a product page you see these massive menus with subcategories (Books > Business > Product Management > Title). In this exercise your job will be to count all of them.

💾  About the dataset

This data warehouse is inspired by an E-commerce website like Amazon. :shopping_cart:

Our E-commerce website allows vendors to sell items in multiple categories. Users can add as many items as they want to a cart and then purchase a cart with/without a discount code. Users also can return items and leave reviews.
