1017. Convert to Base -2

https://leetcode.com/problems/convert-to-base-2

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:** 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

Constraints:

  • 0 <= n <= 109
