Which of the following data structures is typically used to implement DFS?
Step 1: Understand what DFS (Depth First Search) is. It is a method for exploring or searching through data structures like trees or graphs.
Step 2: Know that DFS explores as far down a branch as possible before backtracking.
Step 3: Learn about data structures. A stack is a structure that follows Last In, First Out (LIFO) principle, meaning the last item added is the first one to be removed.
Step 4: Realize that DFS can be implemented using a stack to keep track of nodes to visit next.
Step 5: Understand that recursion can also be used to implement DFS, where the function calls itself to explore deeper nodes, which uses the call stack implicitly.
