Question
When implementing a `Graph` traversal algorithm like
Depth-First Search (DFS) recursively, what is the primary control flow mechanism that manages the order of visiting nodes and backtracking?Solution
In a recursive DFS, the "stack" that manages the order of node visits and backtracking is the program's own call stack. Each recursive call pushes a new frame onto the stack, and when a call returns, its frame is popped, effectively backtracking.
