Client-Server Video and Text | Dataford Interview Questions

Create a client and server that send each other video and text.

Implement simulate_exchange(client_messages, server_messages) as an in-memory exchange. Each input is an array of message maps with type, timestamp, and payload; type is "video" or "text". Return one array containing every message, annotated with its sender as "client" or "server", ordered by nondecreasing timestamp. Preserve input order for messages from the same sender, and place client messages before server messages when timestamps are equal. Do not drop or modify messages.

Constraints

Each message has type, timestamp, and payload fields
type is either "video" or "text"
Messages within each input array are ordered by nondecreasing timestamp
0 <= client_messages.length, server_messages.length
The total number of messages is at most 10^5
Payload values are treated as opaque and must be preserved

Function Signature

def simulate_exchange(client_messages, server_messages):
