WebDepth-First Search (DFS) is an algorithm used to traverse or locate a target node in a graph or tree data structure. It priorities depth and searches along one branch, as far as it can go - until the end of that branch. WebMar 26, 2024 · Depth-first search (DFS) is yet another technique used to traverse a tree or a graph. DFS starts with a root node or a start node and then explores the adjacent nodes of the current node by going deeper into the graph or a tree. This means that in DFS the nodes are explored depth-wise until a node with no children is encountered.
