Questions & Step-by-Step Solutions
What is the primary difference between BFS and DFS in terms of traversal strategy?
Step 1: Understand that BFS stands for Breadth-First Search and DFS stands for Depth-First Search.
Step 2: Know that BFS explores nodes level by level, meaning it visits all nodes at the present depth before moving on to nodes at the next depth level.
Step 3: Learn that BFS uses a queue data structure to keep track of the nodes that need to be explored next.
Step 4: Recognize that DFS explores as far as possible down one branch before backtracking, meaning it goes deep into one path before trying another.
Step 5: Understand that DFS can use a stack data structure or recursion to keep track of the nodes to explore.
