Solution: Parallel Courses III

Understand how to determine the minimum months needed to finish courses with prerequisite relationships using topological sort. Learn to build and process dependency graphs, use in-degree tracking, and update completion times efficiently within a directed acyclic graph structure.

We'll cover the following...

Statement  

You are tasked with determining the minimum time required to complete a set of courses, given their prerequisite relationships and individual durations.

There are n courses labeled from 1 to n. The prerequisite relationships between these courses are provided as a 2D integer array relations, where each entry relations[j]=[prevCoursej,nextCoursej]\text{relations}[j] = [\text{prevCourse}_j, \text{nextCourse}_j] ...
