Design an algorithm to serialize and deserialize a binary tree. There is no restriction on how your serialization/deserialization algorithm should work.

Example 1:

Input: {"root":[1,2,3,null,null,4,5]}

Output: [1,2,3,null,null,4,5]

Constraints:

The number of nodes is in the range $[0, 10^4]$ .
$-1000 \leq \text{Node.val} \leq 1000$

Input

arr ={"root":[1,2,3,null,null,4,5]}

Created root 1
