Which of the following is NOT a characteristic of Depth-First Search?
Step 1: Understand what Depth-First Search (DFS) is. It is a method for exploring a graph or tree by going as deep as possible along each branch before backtracking.
Step 2: Identify the characteristics of DFS. Some key characteristics include: it uses a stack (either explicitly or through recursion), it explores one branch fully before moving to another, and it does not guarantee the shortest path.
Step 3: Recognize that the question is asking for a characteristic that is NOT true for DFS. This means we need to find something that does not apply to DFS.
Step 4: Recall that DFS does not guarantee the shortest path. This is a key point because it means that while DFS explores deeply, it may not find the quickest route to a destination.
Step 5: Conclude that the statement 'DFS guarantees the shortest path' is NOT a characteristic of Depth-First Search.
