I think test 12 contains something like that:
4
1 2 1 3
At least, such test helps in my WA12 :)

My program works for all the test cases given in this thread, but it is giving WA#6, can you please give me this test case?

Mine was wrong because of the test:
17
1 2 12 3 4 7 4 1 5 4 7 8 4 9 10 11 8

(Correct answer is "1 5 4 7 8")

Can anybody give me test #7?

That is not right. Edges should be in the same order as the initial path. In your answer edges are not in the same order. Here is the right one: [1 2 8 9 10 7]
