How does BFS guarantee that it finds the shortest path in an unweighted graph?

  • It always explores the leftmost branch of the graph first.
  • It employs a stack to backtrack and find the shortest path after exploring the entire graph.
  • It uses a priority queue to ensure that nodes are processed in ascending order of their distance from the source.
  • It utilizes a queue and processes nodes in the order they are discovered, ensuring shorter paths are explored first.
BFS guarantees the shortest path in an unweighted graph by using a queue to process nodes in the order they are discovered. Since BFS explores neighbors level by level, the first occurrence of the destination node will yield the shortest path.
