WebMar 17, 2024 · I am trying to use recursion and a 2D array to implement a Depth First Search on an adjacency matrix and having issues. I'm still new to this, sorry if my mistake is too obvious. My code does not read the row if all the numbers are all 0 and doesn't show the components visited. WebJul 6, 2015 · For your implementation, keep track of the left most node and a variable for the depth. Whenever the left most node is popped from the queue, you know you hit a new level and you increment the depth. So, your root is the leftMostNode at level 0. Then the left most child is the leftMostNode. As soon as you hit it, it becomes level 1. ibps rrb officer scale 2 and 3

WebThis recursive nature of DFS can be implemented using stacks. The steps are as follows: Pick a starting node and push all its child nodes into a stack. Pop a node from stack to select the next node to visit and push all its child nodes into a stack. Repeat this process until the stack is empty. Ensure that the nodes that are visited are marked.

WebIn Java, it is possible to represent a graph as a LinkedList of vertices. In this way, each vertex has a LinkedList of edges. An edge is just a pair of two vertices.
