<p><strong>示例 1：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>n = 2
|
||
<strong>输出：</strong>"110"
|
||
<strong>解释：</strong>(-2)<sup>2</sup> + (-2)<sup>1</sup> = 2

<p><strong>示例 2：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>n = 3
|
||
<strong>输出：</strong>"111"
|
||
<strong>解释：</strong>(-2)<sup>2</sup> + (-2)<sup>1</sup> + (-2)<sup>0</sup> = 3
|
||
</pre>

||
<p><strong>示例 3：</strong></p>
|
||
|
||
<pre>
|
||
<strong>输入：</strong>n = 4
|

<p> </p>
|
||
|
||
<p><strong>提示：</strong></p>
|
||
|
||
<ul>
|
||
<li><code>0 <= n <= 10<sup>9</sup></code></li>
|
