This is impractical algorithm, because it would exhaust the stack for large deep trees. There are at least 2 ways to delete the whole tree without using stack or allocating extra memory.

how?

Thank you so much, sir. You have saved my life.

In java, root=null and garbage collection does the rest.

An amazing way to delete any tree, using c++ without any traversal, the language will do the work for us. We can use destructor functionality. #include using namespace std; template class Tree { public: Tree* left; Tree* right; T value; Tree(T value): value(value){ } ~Tree(){ if(left){ delete left, coutleft = new Tree(10); root->right->right = new Tree(10); delete root; return 0; } and there you go no need any traversal at all :__.
