Hi...please i have diffuculties
with this problem...if yu have any ideas help me please.... 2-3 tree Definitions Neighbours: Two nodes are neighbors if they share the same father and does not interfere with node between the pipes. The blue nodes are neighbors but not orange Scalable: A 2-3 tree is scalable if it contains two neighbors where they have three children each Extension: If a tree is scalable get two neighboring nodes with three children each and transformed into three nodes with two children. Implementation: implement the following operations in a 2-3 empty (): returns true if and only if empty contains (x): returns true if and only if it contains the value of x. insert (x): inserts the integer x in the tree isExpandable (): returns true if and only if the tree is extensible expand (): expand the tree (it is call the method immediately after when isExpandable () returns true numberOfNodes (): returns the number of nodes toIntArray (): returns an array of int containing all the tree values in ascending series The Last Two methods are implemented by recursive function calls |
