<p>On a <strong>0-indexed</strong><code>8 x 8</code> chessboard, there can be multiple black queens ad one white king.</p>
<p>You are given a 2D integer array <code>queens</code> where <code>queens[i] = [xQueen<sub>i</sub>, yQueen<sub>i</sub>]</code> represents the position of the <code>i<sup>th</sup></code> black queen on the chessboard. You are also given an integer array <code>king</code> of length <code>2</code> where <code>king = [xKing, yKing]</code> represents the position of the white king.</p>
<p>Return <em>the coordinates of the black queens that can directly attack the king</em>. You may return the answer in <strong>any order</strong>.</p>
<strong>Input:</strong> queens = [[0,1],[1,0],[4,0],[0,4],[3,3],[2,4]], king = [0,0]
<strong>Output:</strong> [[0,1],[1,0],[3,3]]
<strong>Explanation:</strong> The diagram above shows the three queens that can directly attack the king and the three queens that cannot attack the king (i.e., marked with red dashes).
<strong>Input:</strong> queens = [[0,0],[1,1],[2,2],[3,4],[3,5],[4,4],[4,5]], king = [3,3]
