Here i have listed the videos Depth-first search (DFS) is a recursive algorithm, and it is also known as depth-first traversal. The problem with DFS is that this could lead to an infinite loop. This algorithm traverses a graph in a depthward motion and uses a stack to remember to get the next vertex to start a search, when a dead end occurs in any iteration. This is done to avoid infinite loops in cases where the search space is infinite or too large. This algorithm applies to any kind of tree, but since we need an example, we'll use BeautifulSoup, which is a Python module that reads HTML (and related languages) and builds a tree that represents the content. Taking cue from the expert himself, we recognize that without using constraint propagation, that is accounting for What Is DFS (Depth First Search)?
