From 0 to 1 Data Structures & Algorithms in Java - Implementation Of Topological Sort

The video tutorial explains how to perform a topological sort on a graph, including detecting cycles. It covers the implementation of indegree calculation using both adjacency lists and matrices. The tutorial then walks through the topological sort algorithm, detailing how to set up an indegree map, identify vertices with zero indegree, and iteratively build the sorted list. The process also includes cycle detection by checking if all vertices are covered in the sort.

What is the significance of the in-degree map in the topological sort algorithm?

What steps are taken if a vertex's in-degree is reduced to zero?

How can you detect cycles in a graph using topological sort?
