WebFirst, I will build a graph based on the input edges, as the input may not be a binary tree, then I will use DFS to traverse the nodes in the graph. As it's a graph, I need a array to store the status of each node. The status means whether the node has apple or not, whether the node has been visiteed. Status 0 means no apple, status 1 means has ... WebJan 13, 2024 · A Computer Science portal for geeks.

WebDefine the adjacency matrix: The code defines a 2D array graph[NODE][NODE] to represent the adjacency matrix of the graph. It is initialized with values representing the edges between vertices in the graph. Implement the DFS function: The dfs function implements the Depth-First Search algorithm. WebDFS (Depth First Search) algorithm First, create a stack with the total number of vertices in the graph. Now, choose any vertex as the starting point of traversal, and push that vertex into the stack. After that, push a non-visited vertex (adjacent to the vertex on the top of the stack) to the top ... grassy head holiday park
