<H2><A NAME="SECTION0011530000000000000000">Removing Items from an AVL Tree</A></H2>
<P>
The procedure for removing items from an AVL tree
is inherited from the <tt>BST</tt> class in the same way as AVL insertion.
(See Program <A HREF="page319.html#progbst4c" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/html/page319.html#progbst4c"><IMG ALIGN=BOTTOM ALT="gif" SRC="cross_ref_motif.gif" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/icons/cross_ref_motif.gif"></A>).
All the differences are encapsulated in the <tt>DetachKey</tt> and
<tt>Balance</tt> functions.
The <tt>Balance</tt> function is discussed above.
The <tt>DetachKey</tt> function is defined in Program <A HREF="page329.html#progavl5c" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/html/page329.html#progavl5c"><IMG ALIGN=BOTTOM ALT="gif" SRC="cross_ref_motif.gif" tppabs="http://dictator.uwaterloo.ca/Bruno.Preiss/books/opus4/icons/cross_ref_motif.gif"></A>
