WebFeb 18, 2024 · This is a trivial graph problem which can be done with the help of Depth First Search (DFS) or Breadth First Search (BFS). If the graph is not connected, then we will return -1 as it will be impossible to travel between all the nodes. Otherwise, we will move to the next step i.e, to find the minimum travel time. 3. WebAug 4, 2024 · In DFS Traversal, we traverse up to the deepest vertex before backtracking. Since a graph doesn’t have a root node we can select any node s a start node. The node … chem ocr a level

WebJun 23, 2024 · Check if two Nodes are Cousins. Try It! The idea is to find level of one of the nodes. Using the found level, check if ‘a’ and ‘b’ are at this level. If ‘a’ and ‘b’ are at given level, then finally check if they are not children of same parent. Following is the implementation of the above approach. C++. WebDFS of Graph.

Approach: Take the given network as a connected graph with ‘N’ vertices and ‘M’ edges. Let’s assume that the given graph is a rooted tree (with loops), and each loop must have the root node in its path. For such cases, loops can be easily detected with BFS / DFS traversal. But the lengths of loops are also needed, so BFS ... chemo cooling vest
