DFS Program in C – Depth First Search with Example

Posted on by Sandeepa Nadahalli

Depth First Search (DFS) is a graph traversal algorithm that explores as far as possible along each branch before backtracking. Starting from a source node, it follows one path all the way to a dead end, then backtracks and tries the next unvisited neighbor. DFS uses a stack — either an explicit one or the …

BFS Algorithm in C – Adjacency Matrix and List with Example

Posted on by Sandeepa Nadahalli

Breadth First Search (BFS) is a graph traversal algorithm that explores nodes level by level — starting from a source, it visits all immediate neighbors first, then their neighbors, and so on. Because of this level-by-level behavior, BFS always finds the shortest path in an unweighted graph. It is used in GPS navigation, social network …
