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 unexplored path, and then explores it. The algorithm does this until the entire graph has been explored. Many problems in computer … WebMay 18, 2024 · Usage: hdfs dfs -lsr Recursive version of ls. Similar to Unix ls -R. mkdir .
