Problem: N-Queens

Hard
40 min
Explore how to solve the N-Queens II problem by applying backtracking algorithms to count distinct ways of placing n queens on an n x n chessboard so that none attack each other. Understand the problem constraints and implement solutions efficiently within coding exercises.

Statement

Given an integer, n, representing the size of an n x n chessboard, return the number of distinct ways to place n queens so that no two queens attack each other. A queen can attack another queen if they are in the same row, column, or diagonal.

Constraints:

  • 11 \leq n 9\leq 9
