Serialization and Deserialization of an N-ary Tree
Given an N-ary tree where each node has at most 'N' child nodes, the task is to serialize the tree into a sequence of bits and then deserialize it back to reconstruct the original tree.
Serialization involves converting a data structure or object into a format that can be stored or transmitted, while deserialization involves reconstructing the data structure from this format.
Input:
The first line of input contains an integer 'T', denoting the number of test cases.
Each test case consists of elements representing the N-ary tree in a level-order format.
'-1' indicates end of children for a parent node.
The input ends when all nodes at the last level are -1.
Output:
For each test case, output the structure of the deserialized tree after serialization. Each test case result should be on a new line.
Example:
Consider an N-ary tree that is given in level order as follows:
Input: 1 -1 2 3 4 -1 5 6 -1 -1 -1 -1 -1
The deserialized output of this tree should maintain the original tree structure.
Constraints:
1 <= T <= 10
1 <= N <= 10^4
Time limit: 1 second.
Note:
The format provided allows for clarity on the structure of the input tree, though is to be provided in a single, space-separated sequence for processing.
