Preorder Traversal: The Algorithmic Quest

In the realm of binary trees, a brave adventurer such as yourself must traverse the lands in a most particular order.

In Order Traversal - A path of righteousness and justice.
Preorder Traversal - The path we find ourselves on now, where we visit the left, then the node, then the right, in that order.
Postorder Traversal - For those who dare to go the opposite way, a path shrouded in mystery and danger.
Level Order Traversal - A path of breadth-first exploration, where the world is vast and unforgiving.
Depth First Search - A path of reckless abandon, where the unknown lurks around every corner.
Adjacency List - A map of the land, where connections and edges await the brave.
