How It Works: 1) Initialize: Set start node distance = 0, others = ∞. Use a priority queue. 2) Process Nodes: Pick the node with the smallest distance, update neighbors if shorter paths are found. 3) Mark Visited: Mark nodes as visited; don’t revisit. 4) Repeat: Continue until all nodes are visited or target is re
