Understanding the Queens That Can Attack the King Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
On a 0-indexed 8 x 8 chessboard, there can be multiple black queens and one white king. You are given a 2D integer array queens where queens[i] = [xQueeni, yQueeni] represents the position of the ith black queen on the chessboard. You are also given an integer array king of length 2 where king = [xKing, yKing] represents the position of the white king. Return the coordinates of the black queens that can directly attack the king. You may return the answer in any order.
