    • The idea is to generate all possible paths and check whether any path sum is equal to 'K' or not. If the 'ROOT' is NULL, return. Else, add the current node value to a vector. Recur for the left subtree. Recur for the right subtree. Traverse the vector from the back. The last element is taken as the node at which our current path terminates.

Path that visits all nodes

Answer (1 of 2): Yes, all the graph algorithms, including all-paths-shortest-path algorithms like Floyd-Warshall will work with a "complete" graph where every node has an edge connecting it to every other node. If you mean the shortest Hamiltonian Path (which visits each vertex exactly once) the...

    The default key path for each node is ~/.ssh/id_rsa. Note: If you have a private key that can be used across all nodes, you can set the SSH key path at the cluster level. The SSH key path set in each node will always take precedence. SSH Key. Instead of setting the path to the SSH key, you can alternatively specify the actual key, i.e. ssh_key ...The algorithm is useful for analyzing the nodes in a graph and constructing the shortest path of traversing through these. The algorithm traverses the graph in the smallest number of iterations and the shortest possible time. BFS selects a single node (initial or source point) in a graph and then visits all the nodes adjacent to the selected node.

    Check if A is the node that we need. If yes, break dfs. Else, push all the adjacent nodes of A which are not visited into the stack. In this way, we will traverse a path until it is exhausted. Meaning, either there are no adjacent nodes or all the adjacent nodes are already visited. Note:

    true shortest path to target, i.e. for all nodes, then A* search is optimal (always finds the shortest path). Proof Idea: The heuristic is optimistic so it never ignores a good path. As all good paths are explored, we therefore discover the optimal path. A* is optimal

The solution is to attach a "virtual root" to the graph from which all nodes are reachable. This guarantees that DFS visits and assigns parent pointers and start and end times to all nodes.

      • Intuition: BFS levelizes a graph, i.e., at each iteration i it visits the nodes at distance i from the source. Therefore, if the shortest path from source to a node is i, we will definitely find it in iteration i.

    Set the provisional_distance of all nodes from the source node to infinity. Define an empty set of seen_nodes. This set will ensure we don't re-evaluate a node which already has the shortest path set, and that we don't evaluate paths through a node which has a shorter path to the source than the current path.
    • two nodes x and y, there are typically many paths between the two nodes, with each path having a cost. One or more of these paths is a least-cost path.
