What is DFS?

DFS stands for Depth-First Search, which is a special way that computers solve puzzles or search for things. Imagine you’re in a giant maze, and your goal is to find the treasure hidden somewhere inside. But instead of just wandering around, you decide to explore every path as far as you can go before coming back and trying another route. This is exactly what DFS does!

In Depth-First Search, the computer starts at the beginning and moves along a path until it can’t go any further. If it reaches a dead end or finds that there’s no more path to follow, it goes back to the last place where it could make a different choice and then continues from there. The computer keeps doing this until it finds what it’s looking for, like a hidden treasure or a solution to a problem.

DFS is super helpful for solving problems like mazes, puzzles, or even when computers need to check every possible option in a game. It’s like having a very determined explorer who never gives up until every corner has been checked!
