Implementing DFS in Java Depth First Search Algorithm

WebMar 26, 2024 · Iterative DFS. The implementation shown above for the DFS technique is recursive in nature and it uses a function call stack. We have another variation for implementing DFS i.e. “Iterative depth-first search”. In this, we use the explicit stack to hold the visited vertices. We have shown the implementation for iterative DFS below. WebDifference in terms of code execution. An iterative process involves repeatedly executing some code statements using a loop until the problem is solved. In contrast, a recursive process involves solving the problem using smaller sub-problems until the smallest version of the problem (the base case) is reached. Recursion is usually slower due to ...

Introduction to Depth First Search Algorithm (DFS)

WebThere are multiple ways to implement DFS in Java. We will be using an adjacency list for the representation of the graph and will be covering both recursive as well as an iterative approach for implementation of the algorithm. The graph used for the demonstration of the code will be the same as the one used for the above example.
