Dfs c++ using vector
WebJun 21, 2024 · This recursive nature of DFS can be implemented using stacks . The basic idea is as follows: Pick a starting node and push all its adjacent nodes into a stack. Pop a node from stack to select the next node to visit and push all its adjacent nodes into a stack. Repeat this process until the stack is empty. WebMar 26, 2024 · DFS Algorithm. Step 1: Insert the root node or starting node of a tree or a graph in the stack. Step 2: Pop the top item from the stack and add it to the visited list. Step 3: Find all the adjacent nodes of the node …
