 ## Description
+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: a = "11", b = "1"
-Output: "100"
+Input: n = 2
+Output: "110"
+Explantion: (-2)2 + (-2)1 = 2
 ```
