Learn essential coding patterns to answer problems and prepare for tech companies' interviews.

Ace the Java Coding Interview

This module teaches us the underlying patterns behind common coding interview questions. By learning these essential patterns, we'll be able to assess the problem statement and unpack and answer any problem the right way. This approach was created by FAANG’s hiring managers to help us prepare for the typical rounds of interviews at major tech companies like Apple, Google, Meta, Microsoft, and Amazon.

By the end of this module, we'll have the skills we need to unlock even the most challenging questions, grok the coding interview, and level up our career with confidence.

Coding Interview Patterns

# 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` $\leq 1000$
