Algorithms

Given an integer <code>n</code>, return a binary string representing its representation in base <code>-2</code>.

Note that the returned string should not have leading zeros unless the string is <code>&quot;0&quot;</code>.

&nbsp;
Example 1:

<pre>
Input: n = 2
Output: &quot;110&quot;
Explantion: (-2)2 + (-2)1 = 2
</pre>

Example 2:

<pre>
Input: n = 3
Output: &quot;111&quot;
Explantion: (-2)2 + (-2)1 + (-2)0 = 3
</pre>

Example 3:

<pre>
Input: n = 4
Output: &quot;100&quot;
Explantion: (-2)2 = 4
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>0 &lt;= n &lt;= 109</code></li>
</ul>

Math

给你一个整数 <code>n</code> ，以二进制字符串的形式返回该整数的 负二进制（<code>base -2</code>）表示。

注意，除非字符串就是&nbsp;<code>"0"</code>，否则返回的字符串中不能含有前导零。

&nbsp;

示例 1：

<pre>
输入：n = 2
输出："110"
解释：(-2)2 + (-2)1 = 2
</pre>

示例 2：

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

示例 3：

<pre>
输入：n = 4
输出："100"
解释：(-2)2 = 4
</pre>

提示：

<ul>
	<li><code>0 &lt;= n &lt;= 109</code></li>
</ul>
