There is no difference
Questions & Step-by-Step Solutions
What is the main difference in traversal order between BFS and DFS?
Step 1: Understand that BFS stands for Breadth-First Search and DFS stands for Depth-First Search.
Step 2: Know that BFS explores all the nodes at the present depth level before moving on to the nodes at the next depth level.
Step 3: Realize that BFS uses a queue data structure to keep track of the nodes to explore next.
Step 4: In contrast, DFS explores as far down a branch as possible before backtracking to explore other branches.
Step 5: Understand that DFS can use a stack data structure or recursion to keep track of the nodes.
Step 6: Conclude that the main difference is that BFS goes level by level (using a queue), while DFS goes deep into branches (using a stack or recursion).
