JSON Delta python algorithm

Contest Brief

I am looking for a skilled Python developer who can create a JSON Delta algorithm.

The purpose of this algorithm is to generate three Python functions::

1. Generate a delta in JSON format of two separate JSON objects:
When two input JSON objects are passed in. The function should output the delta of the two Python objects in a JSON format (the returned object)
eg function: deltaJSON = generateDelta (<old JSON Object>, <new <JSON Object>)

2. Generate the new JSON data object from the Old JSON data object and the Delta JSON object data.
When the old JSON object data is passed in along with the delta object in JSON format, the new JSON object is generated and returned by the function.
eg function: newJSON = stepForward(<old JSON>,<delta JSON>), returns the newer json object

3. Generate the old JSON object from a New JSON object data and the Delta object data.
eg function: oldJSON = stepBackwards(<new JSON>, <delta JSON>)

I have attached three files to test your three functions:
old.json (contains and older version of a JSON object)
new.json (contains an updated version of a JSON object)
delta.json (contains the delta between the old ("A") and new ("B")

The winner will be the first person to successfully be able to generate the three function and obtain the same results from the supplied three files.

Requirements:
- The output of the delta should be in a specific format as per my requirements.

PS: a JSPN delta is a difference between two JSON objects.
Skills and Experience:
- Expertise in Python programming language.
- Strong understanding of JSON data structures and manipulation.
- Experience in developing algorithms for data generation and comparison.

If you have the required skills and experience, please submit your proposal along with relevant examples of your work.

Please check proposal #27 , which is the most complete and really meets the client's requirements. It implements recursively the requested functions, to completely traverse the json objects.

About stepForward and stepBackwards. Given that the delta already captures both old and new in its data, why do these functions need to receive any other argument except for the delta? The generation of either is fully possible just by extracting only As or Bs from the delta?

Greetings. It seems that values that are the same a simply copied into the delta, whilst differing values get both alternatives included. However, [google_assured_workloads_workload.Content.Attributes.billing_account.Sensitive] is missing from the delta despite being the same for both. On the other hand, [google_assured_workloads_workload.Content.Attributes.billing_account.Type] is included in the delta. Could you explain why that is?
