Questions & Step-by-Step Solutions
What is the primary disadvantage of using DFS?
Step 1: Understand what DFS (Depth-First Search) is. It is a way to explore or search through a graph or tree by going as deep as possible down one path before backtracking.
Step 2: Recognize that in some graphs, there can be very long paths or branches.
Step 3: Realize that DFS will follow these long paths all the way down before checking other options.
Step 4: Identify the problem: If the path is very long and leads to a dead end, DFS may take a long time to backtrack and find other paths.
Step 5: Conclude that this is the primary disadvantage of DFS: it can get stuck exploring deep paths instead of finding shorter or better solutions.
