WebFeb 4, 2015 · Just because tail recursion is not strictly needed does not mean it wouldn't be useful. Recursive solutions are frequently easier to understand than iteration, but the lack of tail calls means recursive algorithms become incorrect for large problem sizes which would blow the stack. ... (similar for DFS though in this case you may avoid ... 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 …
