Processes vs Threads in Linux | Dataford Interview Questions

Can you explain the difference between a process and a thread in a Linux environment?

For a hands-on version, group Linux task records by their thread-group ID, or tgid, and distinguish the process leader from its threads. Implement group_linux_tasks(tasks), which accepts a list of dictionaries containing integer pid and tgid values and returns groups sorted by tgid.

Constraints

1 <= len(tasks) <= 10^5
Each task contains integer fields pid and tgid
Each tgid has exactly one task where pid == tgid
Every pid is unique
Return groups sorted by ascending tgid

Function Signature

def group_linux_tasks(tasks):
