When implementing a `Graph` traversal algorithm like Depth-First Search (DF

Q: Answer-When implementing a `Graph` traversal algorithm like Depth-First Search (DFS) recursively, what is t...

In a recursive DFS, the stack that manages the order of node visits and backtracking is the programs own call stack. Each recursive call pushes a new frame onto the stack, and when a call returns, its frame is popped, effectively backtracking.

S recursively, what is the primary control flow mechanism that manages the order of visiting nodes and backtracking?

A An explicit `Stack` data structure managed by the programmer.

B The implicit call stack maintained by the programming language for function calls.

C A `Queue` data structure for breadth-first exploration.

D A `for` loop iterating over all possible paths.
