WebWhat is depth-first traversal - Depth-first search (DFS) is an algorithm for traversing or searching tree or graph data structures. One starts at the root (selecting some arbitrary node as the root in the case of a graph) and explores as far as possible along each branch before backtracking. Source - Wiki. Example: WebIn RELEASE mode, the Visual Studio generates optimal code and removes the recursion. Instead of ‘call’, the complier translates the tail-recursion using direct jmp which virtually is a loop. It means, that it is not longer a recursion function but you actually code it in recursive form (straightforward).
