Depth-first search (DFS) 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) and explores as far as possible along each branch before backtracking. Extra memory, usually a stack, is needed to keep track of the nodes discovered so far along a specified branch … WebDepth-first search (DFS) is an algorithm for searching a graph or tree data structure. The algorithm starts at the root (top) node of a tree and goes as far as it can down a given branch (path), then backtracks until it finds an …

WebSteps for DFS algorithms: 1. Start by pushing starting vertex of the graph into the stack 2. Pop the top item of the stack and add it to the visited list 3. Create the adjacency list for that vertex. Add the non-visited nodes in the list to the top of the stack 4. Keep repeating steps 2 and 3 until the stack is empty. Depth First Search Algorithm

WebDepth First Search-. Depth First Search or DFS is a graph traversal algorithm. It is used for traversing or searching a graph in a systematic fashion.
