Naukri Job Prerequisite Topological Order
Naukri Job Prerequisite Topological Order
MediumGraphs100% accepted
Naukri lists job skills with prerequisites. Given numCourses and prerequisites[][2] where [a,b] means b must be taken before a, return a valid order to take all courses or [] if impossible. Note: the test data is constructed so each solvable case has exactly one valid order — any correct algorithm produces it.
Approach
Topological sort of courses with prerequisites (Course Schedule II).
