How do I search for a value in a C++ binary search tree?

To search for a value in a C++ binary search tree, you can use a recursive function. Would you like to see an example?

Yes, please provide an example of the code.

Here's a simple example:

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

bool search(Node* root, int value) {
    if (root == nullptr) return false;
    if (root->data == value) return true;
    return value < root->data ? search(root->left, value) : search(root->right, value);
}

This function checks if the value exists in the tree.

What if the tree is empty?

If the tree is empty, the function will return false immediately, as shown in the code. Would you like to know more about handling other cases?
