binary trees using the workshop applet the key values shown in the nodes range from to of coursein real treethere would probably be larger range of key values for exampleif employeessocial security numbers were used for key valuesthey would range up to , , another difference between the workshop applet and real tree is that the workshop applet is limited to depth of fivethat isthere can be no more than five levels from the root to the bottom this restriction ensures that all the nodes in the tree will be visible on the screen in real tree the number of levels is unlimited (until you run out of memoryusing the workshop appletyou can create new tree whenever you want to do thisclick the fill button prompt will ask you to enter the number of nodes in the tree this can vary from to but will give you representative tree after typing in the numberpress fill twice more to generate the new tree you can experiment by creating trees with different numbers of nodes unbalanced trees notice that some of the trees you generate are unbalancedthat isthey have most of their nodes on one side of the root or the otheras shown in figure individual subtrees may also be unbalanced figure unbalanced subtree an unbalanced tree (with an unbalanced subtree
