<p>You are given a circle represented as <code>(radius, xCenter, yCenter)</code> and an axis-aligned rectangle represented as <code>(x1, y1, x2, y2)</code>, where <code>(x1, y1)</code> are the coordinates of the bottom-left corner, and <code>(x2, y2)</code> are the coordinates of the top-right corner of the rectangle.</p>

<p>Return <code>true</code><em> if the circle and rectangle are overlapped otherwise return </em><code>false</code>. In other words, check if there is <strong>any</strong> point <code>(x<sub>i</sub>, y<sub>i</sub>)</code> that belongs to the circle and the rectangle at the same time.</p>

<strong>Input:</strong> radius = 1, xCenter = 0, yCenter = 0, x1 = 1, y1 = -1, x2 = 3, y2 = 1
<strong>Output:</strong> true
<strong>Explanation:</strong> Circle and rectangle share the point (1,0).
