N-Queen Problem

This respository contains the Javascript solution for the N-Queen problem. The current solution utilizes the BFS concept and will be updated with A* algorithm.

• See the result by simply running node main.js
• See different n solution by modifying var solution = new Solution(4) into var solution = new Solution(n); inside main.js

The online animation demo for the N-Queen (BFS approach) is on my CodePen dashboard:
