How can I solve tree problems in C++?

Tree problems in C++ often involve data structures like binary trees or AVL trees. What specific problem are you facing?

I'm trying to implement a binary search tree. What are the basic operations I need?

For a binary search tree, you'll need to implement insertion, deletion, and traversal methods (in-order, pre-order, post-order). Would you like code examples?

Yes, please provide an example of the insertion method.

Here's a simple insertion method for a binary search tree:

struct Node {
    int data;
    Node* left;
    Node* right;
};

Node* insert(Node* root, int data) {
    if (root == nullptr) {
        Node* newNode = new Node();
        newNode->data = data;
        newNode->left = newNode->right = nullptr;
        return newNode;
    }
    if (data < root->data) {
        root->left = insert(root->left, data);
    } else {
        root->right = insert(root->right, data);
    }
    return root;
}

Let me know if you need further assistance!
