binary search tree add code example

Example 1: binary search tree insert java

public static Node insert(Node root, int x){
    if (root == null)
        return new Node(x);
    else if(x>root.getData())
        root.setRightChild(insert(root.getRightChild(),x));
    else
        root.setLeftChild(insert(root.getLeftChild(),x));
    return root;
}

Example 2: insert binary search tree

void BSNode::insert(std::string value) {

	if (this->_data == value) {
		_count++;
		return;
	}

	if (this->_data > value) {
		if (this->getLeft() == nullptr) {
			this->_left = new BSNode(value);
		}
		this->getLeft()->insert(value);
		return;
	}

	if (this->getRight() == nullptr) {
		this->_right = new BSNode(value);
		return;
	}
	this->getRight()->insert(value);
}
