Serialize and Deserialize Binary Tree

Try to solve the Serialize and Deserialize Binary Tree problem.


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.


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