So, it travels like: Step 1) Start from node “1” and visit all the adjacent nodes 2,3,4 Step 2) Mark node 2,3,4 as level 1 and visit their adjacent nodes. It will continue exploring all the adjacent nodes until it reaches the destination node.

WebFor weighted graphs, we'll need Dijkstra 's algorithm. For negative edge cycles, we need Bellman-Ford 's algorithm. Again this algorithm is single source shortest path algorithm. If we need to find out distance from each nodes to all other nodes, we'll need Floyd-Warshall 's algorithm. PDF - Download algorithm for free.
