# Construct the tree

### Explanation: 1. **Node Class Definition**: - The `Node` class is defined exactly as you provided. It initializes each node with a name, an optional parent, and a list of children. - The `__repr__` method is used to provide a string representation of the node and its subtree. 2. **Tree Construction**: - **Root Node**: `root = Node('1')` creates the root of the tree with the name `'1'`. - **Child Nodes**: - `node2 = Node('2', parent=root)` creates a child node `'2'` under the root. - `node3 = Node('3', parent=node2)` creates a child node `'3'` under node `'2'`, making it a grandchild of the root. - `node4 = Node('4', parent=root)` creates another child node `'4'` under the root. 3. **Printing the Tree**: - `print(str(root))` prints the string representation of the entire tree starting from the root. Given the structure, it will output: 
1
2
      (1 (2 3) 4)
### Running the Script To execute the script: 1. Save the code to a file, for example, `print_tree.py`. 2. Run the script using Python: 
1
2
   python print_tree.py
This will display the desired tree structure: 
1
(1 (2 3) 4)

**Explanation:** 1. **Node Class Definition:** - The `Node` class is defined exactly as provided, with an initializer that sets up the node’s name, parent, and children. If a parent is provided, the node is automatically added to the parent’s children list. - The `__repr__` method is used to provide a string representation of the node and its children in the desired format. 2. **Building the Tree:** - **Root Node:** The tree starts with the root node named `'1'`. - **Children of Root:** - Node `'2'` is created with `root` as its parent, making it a child of the root. - Node `'4'` is also created with `root` as its parent. - **Child of Node 2:** - Node `'3'` is created with `node2` as its parent, making it a child of node `'2'`. 3. **Printing the Tree:** - Finally, `print(str(root))` prints the entire tree structure starting from the root. The `__repr__` method ensures it is formatted as `(1 (2 3) 4)`. **Output:** 
1
(1 (2 3) 4)
