This picture is used in the exercise,but no idea of applying it.

    $\begingroup$ I'm not sure this is really directly related to "graph theory". $\endgroup$ – Fabrice NEYRET Jun 7 '16 at 11:56

    $\begingroup$ @Watson Right observation : In fact Hailey has already asked this question 7 hours ago, and this question has been put "on hold". Please Hailey dont' do that, it is not a correct behavior. $\endgroup$ – Jean Marie Jun 7 '16 at 13:10

    $\begingroup$ One of my question should be valid,both are either on hold or duplicate,now how can get the answer. $\endgroup$ – Hailey Jun 7 '16 at 14:11

    $\begingroup$ Since you asked what to do to get an answer - if you read the on-hold banner in your other question, it gives an explanation. "This question is missing context or other details: Please improve the question by providing additional context..." If you click on the text "improve the question", this links brings you to the post (on meta) explaining how good questions should look and what are good ways to add missing context. $\endgroup$ – Martin Sleziak Jun 7 '16 at 14:25
