Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/ahmedshaabanal-saidi/custom_data_structure

A C# implementation of a generic custom data structure named MyList<T> that mimics the behavior of built-in collections. It implements IEnumerable<T>, ICollection<T>, and IList<T>, showcasing a deep understanding of interfaces, generics, and collection manipulation in C#.
