Given an N-ary Tree, Serialize and Deserialize it. Serialization is a basically a representation of a tree in a String format which takes much lesser space than storing the tree itself. Deserialization is constructing the actual tree using the serialized format of the tree. Following is an example of an N-ary Tree. How to serialize and deserialze it? Serialization is to store tree in a file so that it can be later restored. The structure of tree must be maintained. Deserialization is reading tree back from file. This post is mainly an extension of below post. Serialize and Deserialize a Binary Tree. In an N-ary tree, there are no designated left and right children.

Serialization is the process of converting a data structure or object into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network connection link to be reconstructed later in the same or another computer environment.

Design an algorithm to serialize and deserialize a binary tree. There is no restriction on how your serialization/deserialization algorithm should work. You just need to ensure that a binary tree can be serialized to a string and this string can be deserialized to the original tree structure.

Example:

Clarification: The above format is the same as how LeetCode serializes a binary tree. Patch fifa 2008 liga 1 frutti fresh. You do not necessarily need to follow this format, so please be creative and come up with different approaches yourself.

Note: Do not use class member/global/static variables to store states. Your serialize and deserialize algorithms should be stateless.

Given an N-ary Tree, Serialize and Deserialize it. Serialization is a basically a representation of a tree in a String format which takes much lesser space than storing the tree itself. Deserialization is constructing the actual tree using the serialized format of the tree. Following is an example of an N-ary Tree.

Solution

Design an algorithm to serialize and deserialize an N-ary tree. An N-ary tree is a rooted tree in which each node has no more than N children. There is no restriction on how your serialization/deserialization algorithm should work. You just need to ensure that an N-ary tree can be serialized to a string and this string can be deserialized to the original tree structure. Here we have encoded the tree as it's value and the number of children it has in the next level.

Note:

• N is in the range of [1, 1000].
• Do not use class member/global/static variables to store states. Your serialize and deserialize algorithms should be stateless.

In an N-ary tree, there are no designated left and right children. An N-ary Tree is represented by storing an array or list of child pointers with every node.

Following is the serialization and deserialization implementation:
