In this tutorial, I am going to discuss binary tree postorder traversal. How to implement binary tree postorder traversal with and without recursion.
Given the root of a binary tree, write a code to return the postorder traversal of its node’s values.
Given a binary tree, write a code to serialize and deserialize binary tree.
You can choose any algorithm for serialization and deserialization of a binary tree. But make sure the algorithm we choose to serialize a binary tree to a string and can also deserialize the string representation to the original tree structure.
Before solving this problem, let’s first understand what is serialization and deserialization?
In Serialization, the data structure or object is translated/converted into a sequence of bits so that it can be stored in a file or memory buffer, or transmitted across a network.
Deserialization is the process to reconstruct the data structure or object from the sequence of bits.
In this tutorial, i am going to discuss what is binary tree preorder traversal? How to implement binary tree preorder traversal with and without recursion.
Given the root of a binary tree, write a code to return the preorder traversal of its nodes’ values.
