What is Depth-First Search in programming?
Depth-First Search (DFS) is an algorithm for traversing or searching tree or graph data structures. It starts at the root and explores as far as possible along each branch before backtracking.
Can you explain how DFS works with an example?
Sure! Imagine a maze represented as a graph. Starting from the entrance, DFS would explore one path until it hits a dead end, then backtrack and try the next path.
What are the advantages of using DFS?
DFS uses less memory than Breadth-First Search (BFS) and can be more efficient for certain types of problems, like finding a path in a maze.
Are there any disadvantages to using DFS?
Yes, DFS can get stuck in deep paths and may not find the shortest path in unweighted graphs.
