Using BFS and DFS to implement maze path finding

Reference links: Algorithm Basics: Intuitive Explanation of BFS and DFS Maze problem (maze problem) – depth first (DFS) and breadth first search (BFS) solution – Tencent Cloud Developer Community – Tencent Cloud 1. Concept analysis: Introduction to the concepts of BFS and DFS: BFS and DFS are two basic graph traversal algorithms. Breadth-First Search (BFS, […]

Data Structure: Maze Problem (Depth First Search)

Let’s first talk about the problem of developing two-dimensional arrays and one-dimensional arrays. If I want to open a one-dimensional array, DevC++ supports writing code like this #include<iostream> using namespace std; int main() { int n; cin>>n; int a[n]; return 0; } We can enter a variable n to open up an array of how […]
