algorithm - 2-3 trees, data storage -

-

hello i'm trying understand how 2-3 trees work, understood concept keys, store data itself, in leaves, or in nodes 1 key (internal node), , 2 keys (internal node) also, in advance

i'm no expert on tree structure first sentence wikipedia page on 2-3 trees seems answer question data stored:

a 2-3 tree in computer science type of data structure, tree every node children (internal node) has either 2 children , 1 data element (2-nodes) or 3 children , 2 data elements (3-nodes).

seems me store data in each node of tree. wiki page has link java applet demonstrating inserts.

edit: after reading comment, , having sample code, i'm inclined think data , key (as calling it) same thing (as chowlett has mentioned in answer).

looking @ sample code (they storing ints) create twothreenode class holds pointers data storing, ensuring data class has overloaded comparison operators allow them sorted. follow algorithm before.

i found interesting article, source code, here: balanced trees, part 2: interior 2-3 trees

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
