How to iterate through Document Libraries where specific user have access

In a site collection, i have couple of Document libraries like DocA, DocB and DocC. There are couple of users who have permission to access specific Document libraries. For example User A have access to DocA and DocB only and User B have access to DocC only. Now my question is how can I iterate through document libraries for User A only i.e, Document libraries DocA and DocB.

I want sample code to understand?
