Topological Sort
Orders a directed acyclic graph so every dependency precedes its dependent
Why learn Topological Sort?
It schedules builds, courses, and workflow stages
The problem it solves
It converts partial dependency order into a valid linear execution order
Where it came from
Topological Sort is a algorithm that orders a directed acyclic graph so every dependency precedes its dependent. Its guarantees and tradeoffs depend on the concrete implementation and operating context.
Build your understanding
