A binary tree is a data structure where each node has at most two children.
Start by creating a Node class with left and right child pointers.
Implement methods to insert nodes, search for a specific value, and traverse the tree (inorder, preorder, postorder).

To save a binary search tree (BST) to disk, you can serialize the tree and write it to a file.
Serialize the BST using pre-order, in-order, or post-order traversal
Write the serialized data to a file on disk
When reading the data back, deserialize it to reconstruct the BST
