About Graph Problems
Graphs are what you reach for when the coding problems are really about relationships: cities connected by roads, users linked in a network, tasks depending on other tasks, or a complex pathfinding coding challenge.
Once a problem can be described as nodes and edges, graph thinking opens up a lot of powerful tools. Sometimes you need to traverse everything with DFS or BFS. Sometimes you care about the shortest path. Other times it is connected components, cycle detection, topological order, or weighted routes. Graph problems look varied on the surface, but the core patterns repeat a lot.
The big jump in this category is learning how to model the input properly. If you misread the graph type or build the adjacency structure wrong, the algorithm never gets a chance. But once the model is right, the path forward becomes much clearer: traverse, mark visited, relax edges, or process indegrees depending on the problem.
Budibadu gives you graph problems that help you build that modeling instinct and then actually apply the right traversal or pathfinding technique. If you want to get more confident with BFS, DFS, shortest paths, and dependency-style questions, this is a strong category to challenge yourself with.
