Congratulations on completing the Greedy Algorithms roadmap! You now understand:
The greedy approach and when it applies.
Proof techniques: exchange arguments and stays-ahead.
Classic problems: activity selection, intervals, scheduling.
When greedy fails and DP is needed. Recommended next steps:
Dynamic Programming: roadmap for when greedy fails.
Graph Theory: roadmap where many algorithms are greedy (Dijkstra, Prim, Kruskal).
Practice more problems on LeetCode and Codeforces.
