Which traversal method is guaranteed 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 cost, typically considered as 1.
Step 2: Learn about graph traversal methods. The two common methods are Depth-First Search (DFS) and Breadth-First Search (BFS).
Step 3: Know how BFS works. BFS starts at a source node and explores all its neighbors before moving on to the next level of nodes.
Step 4: Realize that by exploring all neighbors at the current depth first, BFS ensures that the first time it reaches a node, it has found the shortest path to that node.
Step 5: Conclude that since BFS explores all nodes at the same depth before going deeper, it is guaranteed to find the shortest path in an unweighted graph.
