Breadth-First Search (BFS) – Iterative and Recursive Implementation

WebFeb 3, 2024 · Make the recursive call for all the adjacent sides, i.e DFS (i + 1, j), DFS (i, j + 1), DFS (i – 1, j) and DFS (i, j – 1) if respective positions are valid i.e., not visited and are within the matrix. Finally, call the function DFS (0, 0) to start the DFS Traversal to print the matrix. Iterative Approach: The idea is to traverse the matrix ... WebDepth-first search (DFS) is a recursive algorithm for traversing a graph. It uses the idea of exhaustive search — it will keep moving deeper into the graph until that particular path is entirely exhausted (in other words, a dead end is found). It is used to solve many interesting problems, such as finding a path in a maze, detecting and ...
