Feature #6: Transmission Error

Explore how to determine if transmission paths in network protocols follow a consistent route or contain multiple diversions. Learn to use two-pointer techniques to check path palindromes, allowing up to one diversion. This lesson helps you understand packet path validation and error detection with optimized Python code.

Description

In our network protocol, response packets take the same route (in reverse) back to the source as the request packet did to the destination. Sometimes the path may differ due to errors, and we can tolerate at most one diversion router. The path, in terms of IDs of routers along the way, is recorded in a list present inside the packet. We need to identify the paths with more than one diversion router, so our topology remains intact and transmission error occurs.

We’ll be provided with a list of integers representing the router IDs. The routers at the start and end of the path will always be the same. The first half of the list will show the request packet’s path from source to the destination, while the second half will show the response packet’s path from the ...
