In the depth-first search (DFS) approach, how is the frontier managed?

As a stack data structure (correct)

As a queue data structure

As a linked list

As a binary tree

What is the catchphrase associated with managing the frontier in depth-first search?

Priority-based removal

First-in first-out

Random removal

Last-in first-out (correct)

The left direction (correct)

One direction randomly

The right direction

Every direction simultaneously
