  1. Uses a queue
  2. Finds the shortest path in unweighted graphs
  3. Can be implemented using recursion
  4. Explores all neighbors before going deeper

Questions & Step-by-Step Solutions

Which of the following is NOT a characteristic of BFS?
  • Step 1: Understand what BFS (Breadth-First Search) is. It is a method for exploring nodes and edges in a graph or tree.
  • Step 2: Know that BFS explores all neighbors of a node before moving to the next level of nodes.
  • Step 3: Identify that BFS uses a queue data structure to keep track of nodes to explore next.
  • Step 4: Recognize that recursion is typically used in DFS (Depth-First Search), not in BFS.
  • Step 5: Conclude that the characteristic of using recursion is NOT a feature of BFS.
