WebOct 26, 2024 · The recursive traversal algorithms work well for implementing tree-based ADT member functions, but if we are trying to hide the trees inside some ADT (e.g., using binary search trees to implement std::set), we may need to provide iterators for walking though the contents of the tree.. Iterators for tree-based data structures can be more … WebAnd following are the two different codes for insertion: This one returns a pointer to the node: node* insertion (node *root, int a) { if (root==nullptr) return newnode (a); else if (adata) root->left=insertion (root->left, a); else root->right=insertion (root->right, a); } This one returns void:
