binary tree preorder traversal?

Draw a binary tree that produces the preorder traversal for the nodes in the following order:

63, 958, 911, 221, 246, 977, 91, 42, 285, 715, 429, 199, 52.

If any one could help me with this I would be very greatful. I have spent the morning trying to understand this concept just not with this list of nodes and would like to see someone else's way of listing these nodes.

Thank you.

    Preorder is root, left child, right child...

    You can literally draw a tree where every successive number is a left child of its' parent and it's technically a correct answer.
