Question
Consider the following C++-like pseudo-code for a binary tree traversal: ```cpp struct Node { int data; Node left; Node right; }; void trickyTraversal(Node root) { if (root == nullptr) { return; } if (root->left != nullptr) { trickyTraversal(root->left); } std::cout << root->data << " "; if (root->right != nullptr) { trickyTraversal(root->right); } } ``` Given the following binary tree: ``` 10 / \ 5 15 / \ / 2 7 12 ``` What will be the output of `trickyTraversal(root)` where `root` points to the node with data `10`?
