The height and size of the Binary Tree are already stored in the root node, but my problem is traversing only the largest path while adding each node to my linked list. ...

Here we go, bear with me. The over-all goal is to return the max alignment between two lists. If there are more than one alignment with the same length it can just return the first. With alignment I mean the elements two lists share, in correct order but not necessarily in order. 1,2,3 and 1,2,9,3; here 1,2,3 would be the longest alignm...

And in general how would one solve this type of path finding? Sample code/pseudo is appreciated. Is there a way to make it interpret the tup...
