Code.hub on Instagram: "Dijkstra’s Algorithm finds the shortest path from a starting node to all other nodes in a weighted graph. It’s used in GPS, network routing, and AI pathfinding. 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
