The services menu of a beauty institute is organized by categories and subcategories.

• Category : 'women'

• SubCategory : 'long hair'

• Service : 'shampoo and haircut'

A category is defined by :

• an id
• a label
• a list of sub categories
• a list of services

A service is defined by :

• an id
• a label
• a price

The menu of the “flexy-developer-backend” institute is described in a json file (servicesMenu.json). You can find this file in the github project.

Write the java code to :

• Load the services menu into a root category
• Search services with a label that matches a given string (the path of each matched services is required)
• Search services with a price under a given threshold (the path of each matched services is required)
• Unit test the written code

A beauty institute also sells products. So it has a products menu too (in another json file). Suggest an evolution of your code so that it can handle products as well.
