Given an integer `n`, return _a binary string representing its representation in base_ `-2`.

**Note** that the returned string should not have leading zeros unless the string is `"0"`.

**Example 1:**

**Input:** n = 2

**Output:** "110" **Explantion:** (-2)2 + (-2)1 = 2

**Example 2:**

**Input:** n = 3

**Output:** "111" **Explantion:** (-2)2 + (-2)1 + (-2)0 = 3

**Example 3:**

**Input:** n = 4

**Output:** "100" **Explantion:** (-2)2 = 4
