Dsa Graphs in Dsa

A graph is a set of nodes (vertices) connected by edges. It models roads, social networks, web links and dependencies. We usually store it as an adjacency list (a dict of node → list of neighbours). Graphs can be directed or undirected, weighted or unweighted.

Two core traversals: Breadth-First Search (BFS) explores level by level using a queue — it finds the shortest path in an unweighted graph. Depth-First Search (DFS) goes as deep as possible using recursion or a stack — great for cycle detection, topological sort and connected components. Both are O(V + E).
