In Delete operation of Binary Search Tree, If a node is a leaf node then that will be directly remove and If a node have a single successor then replace that node with that successor. Select one: True False code example

Example: binary tree deletion

/* This is just the deletion function you need to write the required code.
	Thank you. */

void deleteNode(Node *root, int data)
{
    if(root == NULL)
    {
        cout << "Tree is empty\n";
        return;
    }

    q.push(root);

    while(!q.empty())
    {
        Node *temp = q.front();
        q.pop();

        if(temp->data == data)
