Feature #2: Serialize and Deserialize Participant Data
Implementing the "Serialize and Deserialize Participant Data" feature for our "Zoom" project.
We'll cover the following
Like in the previous feature, the participant data of a Zoom session is maintained using a binary search tree. This is beneficial because the sorted order of names on the display does not change even when participants join or leave the meeting. We’ll assume that this binary search tree is maintained on both the server and client sides. However, while transmitting this information back and forth, we also want to serialize the data, send it from the server to the client, and then deserialize the data received by the client into a BST. Therefore, we need to create two modules: a serializer that serializes the data before sending it through the network and a deserializer that translates the serialized data into its original form.
There are many ways to represent a serialized representation of a binary search tree. All that matters is that it is optimized.
Let’s look at an example of serializing a binary search tree. Suppose we are given the following tree as input:
