Depth-First Search (DFS)

Depth-First Search (DFS) is a method used to explore all the points (or nodes) in a network (or graph) by starting at a specific point and diving deep into one path as far as possible before backtracking to explore other routes. Imagine following a trail through a maze: you go forward until you can't go further, then turn back to explore different paths. DFS helps systematically visit every node, making it useful for tasks like finding connections, detecting cycles, or solving puzzles where exploring one complete route at a time is effective.
