Solution: Course Schedule

Explore how to solve the Course Schedule problem by implementing topological sort and depth-first search algorithms. Understand how to represent course prerequisites as directed graphs and manage in-degree counts to detect cycles. This lesson helps you develop skills to decide if all courses can be finished based on their dependency relationships, improving your coding interview preparation.

Statement

You are given an integer, numCourses, representing the total number of courses you need to complete, labeled from 0 to numCourses - 1.

You are also given a prerequisites array, where prerequisites[i] = [a[i], b[i]] indicates that you must take course b[i] first if you want to take the course a[i]. For example, the pair [1,0][1, 0] indicates that to take course ...
