If u = '0' then just remove it, i.e. U := U \ {u} If u = '1' then start exploration DFS (u, U) Where procedure DFS (u, U) uses the matrix to explore the '1' neighbours of u.

WebMar 28, 2024 · Depth-first search is an algorithm for traversing or searching tree or graph data structures. The algorithm starts at the root node (selecting some arbitrary node as the root node in the case of a graph) … WebTime & Space Complexity. The running time complexity of the DFS algorithm in java is O(V+E) where V is the number of nodes in the graph, and E is the number of edges. Since the algorithm requires a stack for storing the nodes that need to be traversed at any point in time, the space complexity is the maximum size of the stack at any point of time.
