Given the edges in a graph which is a cycle, like edges 1 2 3 1 2 4 4 5 5 6 6 7 7 8 9 8 10 9 11 10 11 12 12 13 14 15 15 16 17 3 18 17 18 19 20 19 20 21 21 22 22 14 16 23 13 24 25 24 26 25 23 26 Vertices of the graph are represented by >:i.26 Question is how to determine in an elegant way the sequence of vertices along the cycle, which is 1 2 4 5 6 7 8 9 10 11 12 13 24 25 26 23 16 15 14 22 21 20 19 18 17 3 1
