How do you perform preorder traversal in a given binary tree in C++


🤖 Code Explanation

This code is written in C++ and creates a struct called node. The node struct has two members, data and left and right pointers. The code then defines a newNode function which takes an integer as a parameter and creates a new node struct with the given data. The code also defines a preorder function which prints the data in a node struct and then calls the preorder function on the left and right child nodes.
