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 19, 2024 · To implement the DFS we use stack and array data structure.
