**Inverting a Binary Tree**

Given the following **Binary Tree**, reverse the tree as shown in the diagram below. Similarly, invert the tree (or turn upside down) and return to its root.

### Diagram Explanation:

The diagram shows two binary trees.

- The **left tree** has the following structure:
- Root node with value 4.
- Two child nodes from the root: Left child with value 2 and right child with value 7.
- Node 2 has two children: Left child with value 1 and right child with value 3.
- Node 7 has two children: Left child with value 6 and right child with value 9.

- The **right tree** is the inverted version of the left tree:
- Root node with value 4.
- Two child nodes from the root: Left child with value 7 and right child with value 2.
- Node 7 has two children: Left child with value 9 and right child with value 6.
- Node 2 has two children: Left child with value 3 and right child with value 1.

### Solution Approach:

The solution can be achieved using a **Recursive method** or function. Alternatively, an **iterative method** can be used to combine both solutions within your code.

### Code Definition:

```cpp
/**
* Definition for a binary tree node.
* struct TreeNode {
* int val;
* TreeNode *left;
* TreeNode *right;
* TreeNode() : val(0), left(nullptr), right(nullptr) {}
* TreeNode(int x) : val(x), left(nullptr), right(nullptr) {}
* TreeNode(int x, TreeNode *left, TreeNode *right) : val(x), left(left), right(right) {}
* };
*/

class Solution {
public:
TreeNode* invertTree(TreeNode* root) {
// Implementation goes here
}
};
```

This code snippet defines the structure for a binary tree node and outlines the function to invert a binary tree. The `invertTree` function is currently a placeholder for the actual implementation.

Expert Solution

Step 1

Binary Tree :

A binary tree, also known as the left child and the right child, is a type of tree data structure used in computer science where each node can have up to two children.

Recursive Solution :

It is simple to recursively solve one of the most well-known interview questions. The plan is to move through the tree in a preorder approach, swapping each node's left and right child before recursively inverting its left and right subtree for each node that is encountered. The tree can also be navigated in a postorder method.
