OPTION A (Basic): Soft Deletion in Trees
You are going to be changing the general tree class template,FHtree, of the lectures by adding a single memberto it:
boolean deleted; // true if the node has been removed from the tree
The idea is that when a client asks this class to delete a node,all we will do is set this boolean to true andreturn without further ado.
You will have to rename the classes fromFHtreeNode and FHtree (from thelectures) to FHsdTreeNode andFHsdTree, respectively, to distinguish them fromthe normal-deletion implementations in those lectures.
That’s it in a nutshell. The purpose of this new,deleted, member
