Explanation
- The **Winged Edge** data structure is used to represent **polygonal meshes** and is a way to store a topological representation of the mesh. It associates edges with the two adjacent faces and the vertices connected by those edges. This data structure is particularly useful in computer graphics, computational geometry, and mesh processing.

Steps
- Each edge stores references to its two adjacent faces.
- Each face stores references to the edges that form it.
- Vertices are associated with the edges they connect.
- Use the edges to traverse around the mesh and perform operations like splitting or merging faces.

Time Complexity
