I’ve been struggling a lot on this exercise.
I would like to represent the undirected graph G from the vector in the picture but I tried for one hour and it doesn’t fit with the correction.
Indeed, the correction says that there are 3 connected components, respectively with 3, 3 and 6 vertices and that it’s not possible to have a connection between 5-8, 8-12, 5-12, 11-6 and 0-13.

I would really appreciate your help!
