given this methodwe perform insert( ,xfor dictionary implemented with binary search tree by calling treeinsert( , , root())which is given in code fragment code fragment recursive algorithm for insertion in binary search tree this algorithm traces path from ' root to an external nodewhich is expanded into new internal node accommodating the new entry an example of insertion into binary search tree is shown in figure figure insertion of an entry with key into the search tree of figure finding the position to insert is shown in ( )and the resulting tree is shown in (bremoval
