Questions & Step-by-Step Solutions
In a graph, if you want to check if there is a path between two nodes, which traversal method would be more suitable?
Step 1: Understand what a graph is. A graph consists of nodes (or vertices) connected by edges.
Step 2: Identify the two nodes you want to check for a path between.
Step 3: Learn about traversal methods. The two common methods are Breadth-First Search (BFS) and Depth-First Search (DFS).
Step 4: Know that BFS explores all neighbors of a node before moving to the next level, while DFS goes as deep as possible down one path before backtracking.
Step 5: Realize that both BFS and DFS can find a path between two nodes.
Step 6: Understand that BFS is better for finding the shortest path because it explores all possible paths level by level.
Step 7: Conclude that if you want to check for a path and possibly find the shortest one, use BFS.
