I had absolute fun solving this problem statement. Found couple of edge cases, have added conditions for them too. There's a basic input validation at start to check if both email and phonenumber is not null. And then a function to validate both email and phonenumber.

Edge Case I found

Handling Nested Secondary Contacts

When creating a new contact using a secondary email or phone number, ensure that these details have not been used by the primary contact linked to this record.

Example:

• Primary Contact

  • Email: [email protected]
  • Phone Number: 123

• Secondary Contacts

  • Email: [email protected], Phone Number: 789
  • Email: [email protected], Phone Number: 789

The goal is to manage cases where the secondary contact’s email or phone number overlaps with other contacts.
