In a graph, if all edges have the same weight, which algorithm can be used to find the shortest path?
Step 1: Understand that a graph consists of nodes (or vertices) connected by edges.
Step 2: Recognize that when all edges have the same weight, it means each edge contributes equally to the path length.
Step 3: Learn that Breadth-First Search (BFS) is a method used to explore the graph level by level.
Step 4: Realize that BFS will find the shortest path in an unweighted graph (or a graph with equal edge weights) because it explores all nodes at the present depth before moving on to nodes at the next depth level.
Step 5: Conclude that since BFS explores all possible paths equally, it guarantees finding the shortest path when all edges are the same.
