(ac (bfigure dynamic general tree representation with linked lists of child pointers (athe general tree (bthe tree representation root ( (bfigure converting from forest of general trees to single binary tree each node stores pointers to its left child and right sibling the tree roots are assumed to be siblings for the purpose of converting compared with the implementation illustrated by figure which requires overhead of three pointers/nodethe implementation of figure only requires two pointers per node because each node of the general tree now contains fixed number of pointersand because each function of the general tree adt can now be implemented efficientlythe dynamic "left-child/right-siblingimplementation is preferred to the other general tree implementations described in sections to -ary trees -ary trees are trees whose internal nodes all have exactly children thusa full binary tree is -ary tree the pr quadtree discussed in section is an
