Package kkchengaf.EnchantmentOrder

Class BinaryTree

java.lang.Object
kkchengaf.EnchantmentOrder.BinaryTree
public class BinaryTree extends Object
The underlying tree structure of a search result,
it stores a reference to the result data after constructor,
buildTree(): Node, build the tree structure for later traversal,
parseTree(inputHashMap): Integer, assign the data to all the tree nodes,
traversal(node, callback): Boolean, post-order traversal and callback non leaf node
