Serialization/Deserialization of a Binary Tree | LeetCode

Design an algorithm and write code to serialize and deserialize a binary tree. Writing the tree to a file is called ‘serialization’ and reading back from the file to reconstruct the exact same binary tree is ‘deserialization’.

Being able to store a binary tree to a file presents lots of benefits. First, we are able to save the binary tree to a file and restore it at a later time. We are also able to transmit the binary tree representation via network and load it into another computer. Without doubt, serialization/deserialization of a binary tree is important and an algorithm to represent a binary tree in a compact way is very desirable.
