Webb24 mars 2024 · Recursive DFS Let’s introduce the recursive version of the DFS algorithm. Take a look at the implementation: First of all, we define the array that will be initialized with values. The use of the array is to determine which nodes have been visited to prevent the algorithm from visiting the same node more than once. Webb9 maj 2024 · 1 Answer Sorted by: 2 Well, your code is indeed doing DFS and it is doing tail recursion. I don't see any improvement from an algorithm perspective. One low-hanging fruit is to get rid of seen_nodes as it seems to exist only for debugging purposes.
