bst to insert tree

struct Node

    int data;
    Node *left, *right;
};
 
// Function to create a new binary tree node having a given key
Node* newNode(int key)
{
    Node* node = new Node;
    node->data = key;
    node->left = node->right = nullptr;
 
    return node;
}
 
// Function to perform inorder traversal on the tree
void inorder(Node* root)
{
    if (root == nullptr) {
        return;
    }
 
    inorder(root->left);
    cout << root->data << " ";
    inorder(root->right);
}
 
// Recursive function to insert a key into a BST
Node* insert(Node* root, int key)

    if (root == nullptr) {
        return newNode(key);
    }
 
    // if the given key is less than the root node, recur for the left subtree
    if (key < root->data) {
        root->left = insert(root->left, key);
