📄️ Cycle Detection
Detecting & printing a negative cycle with Bellman–Ford
📄️ Idea and algorithm
We need the k = 1…10 cheapest path costs from city 1 to city n in a directed, non-negative graph (n≤100,000, m≤200,000).
📄️ Message Route
3. Path reconstruction is fragile – use a parent array
📄️ Round Trip II — find any directed cycle
1. Key observation
📄️ Counting Rooms
Problem Statement
📄️ Introduction
Graph algorithms are fundamental to competitive programming and computer science. They help solve problems involving relationships between objects, networks, and complex data structures.
📄️ labyrinth
The program you posted is a classic breadth-first-search (BFS) + back-tracking solution—the standard way all competitive-programming editorials solve the CSES “Labyrinth” task.
