6 General Trees 6.1 The following algorithm is linear on the size of the two trees. // Return TRUE iff t1 and t2 are roots of identical // general trees template <class Elem> bool Compare(GTNode<Elem>* t1, GTNode<Elem>* t2) { GTNode<Elem> *c1, *c2; return false; if ((t1 == NULL) & (t2 == NULL)) return true; if (t1->val() != t2->val()) return false; c1 = t1->leftmost_child(); c2 = t2->leftmost_child();
