C++, Java DSA Specialist Needed

As a client in need of an experienced DSA specialist, I have a project requiring mastery in C++ and Java programming languages. This assignment will encompass:

- The design and analysis of algorithms
- The implementation of data structures

Ideally, I'm on the lookout for an expert with proven knowledge and experience in the implementation of the following data structures:

- Arrays
- Linked lists
- Stacks and queues

This project requires precision and efficiency, therefore requiring a freelancer who can demonstrate comprehensive understanding and practical usage of these languages and data structures.
