The function, BFS(), takes three arguments: the graph to traverse, the start node, and the end node. It should retun a shortest path from start to node, inclusive, as a list. For example, given the graph below, BFS(graph, e, 6) should return [e, 1, 6] or to, 5, 6]. If there is no path, return an empty list, [0 1. Create an empty set of closed nodes and an empty dictionary to store each node's parent 2. Initialize the open queue to contain the start node 3. While the open queue is not empty, dequeue the next node from the open queue and set it to the current node 1. If it is the goal node, reconstruct the path back to the start using the parent mapping 2 Otherwise, for each of its neighbors, add it to the open queue if it's not in there or in the closed set and store the current node as its parent. Add the current node to the set of closed nodes. 4. If you empty the open queue without reaching the goal node, there is no path 2: 0 0 6 0 12-30 PM (up
