Hi, I need to do a depth first search tree for the following undirected graph:

1-2-3

|...|..|

4-5 6

|......|

7-8-9

(Sorry about the graph being so unclear, the dots are just to space the lines out). It says to start at A which I'm guessing is 1?

My first attempt at the order was 1-4-7-8-9-6-3-2-5 but I'm really not sure?
