The following algorithm shows how a forest can be represented by a single binary tree. Algorithm 11.8 The Natural Mapping of a Forest into a Binary Tree 1. Map the root of the first tree into the root of the binary tree. 2. If node X maps into X' and node Y is the first child of X, then map Y into the left child of X'. 3. If node X maps into X' and node Z is the sibling of X, then map Z into the right child of X'. The roots of the trees themselves are considered siblings.

EXAMPLE 11.26 Mapping a Forest into a Binary Tree
Figure 11.24 is the mapping of the forest shown in Example 11.25. For example, in the original forest, C has oldest child F and next sibling D. In the corresponding binary tree, C has left child F and right child D. Figure 11.24 The natural mapping of a forest into a binary tree
