<p>A <strong>valid cut</strong> in a circle can be:</p>

<ul>
	<li>A cut that is represented by a straight line that touches two points on the edge of the circle and passes through its center, or</li>
	<li>A cut that is represented by a straight line that touches one point on the edge of the circle and its center.</li>
</ul>

<p>Some valid and invalid cuts are shown in the figures below.</p>

<p><strong class="example">Example 1:</strong></p>
<img alt="" src="https://assets.leetcode.com/uploads/2022/10/24/11drawio.png" style="width: 200px; height: 200px;" />
<pre>
<strong>Input:</strong> n = 4
<strong>Output:</strong> 2
<strong>Explanation:</strong> 
The above figure shows how cutting the circle twice through the middle divides it into 4 equal slices.

<img alt="" src="https://assets.leetcode.com/uploads/2022/10/24/22drawio.png" style="width: 200px; height: 201px;" />
<pre>
<strong>Input:</strong> n = 3
<strong>Output:</strong> 3
<strong>Explanation:</strong>
At least 3 cuts are needed to divide the circle into 3 equal slices. 
It can be shown that less than 3 cuts cannot result in 3 slices of equal size and shape.
Also note that the first cut will not divide the circle into distinct parts.
