WebAnother way of defining binary trees is a recursive definition on directed graphs. A binary tree is either: A single vertex. A graph formed by taking two binary trees, adding a vertex, and adding an edge directed from the new vertex to the root of each binary tree. This also does not establish the order of children, but does fix a specific root ... WebJun 1, 2011 · The last resort would be making your data model more flexible. You would have to skip nearly all assertions and base your data model on a full blown graph. As the above example shows, it is easily possible to be your own grandfather, so you can even have cycles. In this case, you should extensively test your software.
