Problem: Serialize and Deserialize Binary Tree

Medium

30 min

Explore methods to serialize a binary tree into a list of integers and then deserialize it back into the original tree using depth-first search. Understand how to maintain tree integrity and efficiently reconstruct tree structures while working with common constraints. Practice implementing this pattern for coding interviews.

Statement

Serialize a given binary tree to a file and deserialize it back to a tree. Make sure that the original and the deserialized trees are identical.

Serialize: Write the tree to a file.
Deserialize: Read from a file and reconstruct the tree in memory.

Serialize the tree into a list of integers, and then, deserialize it back from the list to a tree. For simplicity’s sake, there’s no need to write the list to the files.

Constraints:

The number of nodes in the tree is in the range $[0, 500]$ .
$-1000 \leq$ Node.value $\leq 1000$
