How to create a project using CSI $260$ Programming Data Structures and Algorithms.

Using C#

I want to create a project as a programmer for an Apple company concerning an Apple Phone and Tablet for a cell. How do I create a project with full codes for marketing using C# language? I want to implement the Doubly LinkedList data structures into this project. And it must be custom$-$built, not just using the built$-$in library. For additional information, use the following data.

Criteria

Project Relevance and Complexity: $-$Assesses how well the project aligns with industry standards and job relevance. Complexity should demonstrate the ability to solve significant problems.

Implementation of Data Structures: $-$ Evaluate the custom implementation of data structures or algorithms, showcasing an understanding of their concepts and the ability to build from scratch.

Code Quality and Documentation: $-$ Consider the cleanliness of the code, the presence of meaningful comments, and comprehensive documentation including a README that clearly explains the project's setup, usage, and features.

Project Innovation and Problem$-$Solving: $-$ Rewards creative solutions to problems, the use of technology in novel ways, and the project's ability to address real$-$world issues.

Continuous Improvement and Learning: $-$ Evaluate evidence of ongoing project refinement, feature additions, adaptation to feedback, and learning of new skills through the project. This category now also reflects the importance of being open to learning from the community and integrating feedback to improve. Thank You so much!!
