As when connecting the Warren Truss Vertices, we should proceed step by step to add each of the five categories of edges: the top orange edges, the bottom green edges, the black vertical edges, the purple diagonally up edges $($on the left side of the bridge$)$ and the pink diagonally down edges $($on the right side of the bridge$).$

In the example above there are $6$ segments, so there will be $3$ purple edges and $3$ pink edges. However, your code should work for any $($even$)$ number of segments.

The switch from diagonally up to diagonally down always happens at the midpoint of the bridge. A Howe Truss bridge must therefore always consist of an even number of segments.

Task $8$: Implement the connect$\_$howe$\_$truss$\_$vertices function in the code cell below.
