<p>给你两个正整数 <code>X</code> 和 <code>Y</code> 和一个二维整数数组 <code>circles</code> ，其中 <code>circles[i] = [x<sub>i</sub>, y<sub>i</sub>, r<sub>i</sub>]</code> 表示一个圆心在 <code>(x<sub>i</sub>, y<sub>i</sub>)</code> 半径为 <code>r<sub>i</sub></code> 的圆。</p>
|
||
|
||
<p>坐标平面内有一个左下角在原点，右上角在 <code>(X, Y)</code> 的矩形。你需要判断是否存在一条从左下角到右上角的路径满足：路径 <strong>完全</strong> 在矩形内部，<strong>不会</strong> 触碰或者经过 <strong>任何</strong> 圆的内部和边界，同时 <strong>只</strong> 在起点和终点接触到矩形。</p>
|
||
|
||
<p>如果存在这样的路径，请你返回 <code>true</code> ，否则返回 <code>false</code> 。</p>
