WebMar 14, 2024 · Depth-first search (DFS) is a technique that is used to traverse a tree or a graph. DFS technique starts with a root node and then traverses the adjacent nodes of the root node by going deeper into the graph. In the DFS technique, the nodes are traversed depth-wise until there are no more children to explore.
