# Print the tree
print(str(root))
### Explanation: 1. **Node Class**: The `Node` class represents a node in the tree. Each node has a `name`, a `parent`, and a list of `children`. The `__repr__` method is overridden to provide a string representation of the tree structure. 2. **Tree Construction**: The tree is constructed by creating nodes and specifying their parents. For example, `node2` is a child of `root`, and `node3`, `node4`, `node5`, and `node6` are children of `node2`. 3. **Printing the Tree**: The `str(root)` call invokes the `__repr__` method of the `root` node, which recursively constructs the string representation of the entire tree. ### Output: When you run this script, it will print the following tree structure: 
1
(1 (2 (3 4 5 6) (7 8)) (9 10 (11 12)))
This matches the desired output.

node10 = Node('10', node9)
node11 = Node('11', node10)
node12 = Node('12', node10)

# Print the tree
print(str(root))
And got the output: (1 (2 3 4 5 6 (7 8)) (9 (10 11 12)))

Substring Evaluation

Testing if the previous output contains the string (1 (2 (3 4 5 6) (7 8)) (9 10 (11 12))): False
