let’s go back to rethinking about how |
||||||||||||
| we
organize our nodes |
|||||||||||||
| – | maybe
instead of trying to balance the tree we |
||||||||||||
| keep
the tree balancing at all times (perfectly |
|||||||||||||
| balanced) |
|||||||||||||
| – | but
the 2-3 tree had a flaw in that there may be |
||||||||||||
| situations
where each node is “full” requiring a |
|||||||||||||
| rippling
effect of nodes being split as you |
|||||||||||||
| recursively
return back to the root |
