Webb21 okt. 2024 · The depth-first search (DFS) is a tree traversal technique. In DFS, we go as deep as possible down to one path before we explore or visit the different node or the next sibling (It’s like a maze; you go to one end before exploring other side). Here is how the depth-first search will traverse the tree starting from root node. metric conversion inches to feet

The nature of a queue and a stack are pretty much opposite, so trying to use the call stack (which is a stack, hence the name) as the auxiliary storage (a queue) is pretty much doomed to failure.
