Day 157: Course Schedule II
DFS + Topological Sort
Find valid order of courses, detect cycle
#LeetCode #Graph #DFS #TopologicalSort
Day 84/365
Solved LeetCode Q210 today.
Course Schedule II.
Topological sort makes these dependency problems feel really elegant.
Graphs are getting more intuitive now.
