The N-Queens Problem Explained | Backtracking Algorithm | 4-Queens Example #daa #codewithash

In this video, we tackle the famous N-Queens Problem using the Backtracking approach.

We start by explaining the fundamental rules of the problem and move directly into a detailed, step-by-step solution for the 4-Queens problem. You will see exactly how the algorithm places a queen, checks for safety, and backtracks when it hits a dead end.

What we cover in this video:

The Rules: Why no two queens can share the same row, column, or diagonal.

The Logic: How the State-Space Tree helps us find the solution.

4-Queens Example: A full walkthrough on a 4x4 grid.

The Algorithm: Understanding the isSafe() function and the recursive process.

Complexity: A look at the time and space complexity of N-Queens.
