以下是对给定代码进行注释的解释：
”`cpp void insertNodeInThreadedTree(TreeNode*& root, int position, int value) {
if (root == nullptr)return;TreeNode* newNode = new TreeNode();newNode->val = value;TreeNode* curr = root; // 当前结点指针while (curr != nullptr) {// 判断当前位置是否为指定位置if (position == 1 && curr->isThreaded && curr->left != nullptr && curr->left->isThreaded) {newNode->left = curr->left; // 新节点的左孩子为当前结点的前驱（线索）newNode->right = curr; // 新节点的右孩子为当前结点curr->left = newNode; // 当前结点的前驱指向新节点curr->isThreaded = false; // 当前结点不再为线索return;} else if (position == 2 && curr->isThreaded && curr->right != nullptr && curr->right->isThreaded) {newNode->right = curr->right; // 新节点的右孩子为当前结点的后继（线索）newNode->left = curr; // 新节点的左孩子为当前结点curr->right = newNode; // 当前结点的后继指向新节点curr->isThreaded = false; // 当前结点不再为线索return;}if (!curr->isThreaded)position -= 2;if (curr->left != nullptr && !curr-<br/><br/><br/><font size=1 color=#CCCCCC>内容由零声教学AI助手提供，问题来源于学员提问</font>
