Answer 1

Answer #1

Eulerian cycle is a cycle which starts and ends at the same graph vertex including all other vertices exactly once.
In other words, it is a graph cycle which uses each graph edge exactly once

Eulerian cycle in this graph is
1 -> 2 -> 4 -> 8 -> 5 -> 10 -> 12 -> 11 -> 9 -> 7 -> 6 -> 3 -> 1
