N-Queens Problem

Place N queens on an N×N chessboard such that no two queens threaten each other.

Time Complexity

O(N!)

Space Complexity

O(N²)

Approach

Place queens column by column, backtrack when conflicts arise.

📚 Backtracking Concepts

1. Choice

Try placing a value at the current position.

2. Constraint

Check if the placement violates any rules.

3. Goal

Have we solved the problem? If not, continue or backtrack.
