Format of OJ binary trees?

Question

I know there was a specification how trees used for OJ input data are represented as an array, but I can't seem to find it anywhere. Is there a link? If I have a tree

        5
      /   \
    4     7
  /       /
 3      6

would an array representation be {5, 4, 7, 3, #, 6, #}?

Is there perhaps an already made java parser for that? :)

Answer 1

Here it is.

Answer 2

No. the array should be {5, 4, 7, 3,#, 6,#}. The result is traverse the tree by level.

No, your answer is wrong.
