  # AVL-Tree
  
  This implementation of an AVL Tree has been uploaded to [rosettacode.org](https://rosettacode.org).
  
  It was initially a translation of the Java version on Rosetta Code. In addition to the translated code, other public methods have been added as shown by the leading asterisk in the following list of all public methods:
  
  * insert node
  * delete node
  * show all node keys
  * show all node balances
  * \*delete nodes by a list of node keys
  * \*find and return node objects by key
  * \*attach data per node
  * \*return list of all node keys
  * \*return list of all node objects
  
  ## Synopsis
  
  See the example in the Github repository and on Rosetta Code.
  
  ```
  #!/usr/bin/env perl6
  
  use AVL-Tree;
  # ...create a tree and some nodes...
  my $tree = AVL-Tree.new;
  $tree.insert: 1;
  $tree.insert: 2, :data<some important tidbit of knowledge>;
  $my $n = $tree.find: 2;
  say $n.data;
  some important tidbit of knowledge
  
  ```
