WebMay 23, 2024 · Depth-first search (DFS) is a traversal algorithm used for both Tree and Graph data structures. The depth-first search goes deep in each branch before moving to explore another branch. In the next sections, we'll first have a look at the implementation for a Tree and then a Graph. To see how to implement these structures in Java, have a look …
