WebNow node 2 is visited and dist b/w 0 and 1 is updated to the value 3 using the path 0->2->1, but since node 1 is marked visited, you cannot change the distance b/w 0 and 3 which (using the optimal path) (`0->2->1->3) is 4. So, your algorithm fails without using the priority_queue. It reports dist b/w 0 and 3 to be 6 while in reality it should be 4.
