I don't know why, but you may use unsigned integer and give it a try.
Cause I got accept use unsigned int. ^^
And maybe if the node was a leaf, you should printf two of them.
For example,
the case node 5
you should print 5 5

hope this would do you good
if you have some other problem, you could consult me
