Which traversal method is typically used to find the shortest path in an unweighted graph?
Step 1: Understand what an unweighted graph is. An unweighted graph is a graph where all edges have the same weight or no weight at all.
Step 2: Learn about traversal methods. Traversal methods are ways to visit all the nodes in a graph.
Step 3: Identify the two common traversal methods: Depth-First Search (DFS) and Breadth-First Search (BFS).
Step 4: Recognize that BFS explores all neighbors of a node before moving deeper into the graph. This means it looks at all nodes at the current level before going to the next level.
Step 5: Understand that because BFS explores level by level, it guarantees that the first time it reaches a node, it has found the shortest path to that node in an unweighted graph.
Step 6: Conclude that BFS is the preferred method for finding the shortest path in an unweighted graph.
