Binary Tree

Construct an algorithm that converts a binary tree into a string representation and another that reconstructs the original tree from that string. The format of the string is your design choice, but the round-trip must be lossless.

Examples

Example 1:

Input:root = [3,1,5,null,null,2,7]

Output:[3,1,5,null,null,2,7]
