Given a number N
, return a string consisting of "0"
s and "1"
s that represents its value in base -2
(negative two).
The returned string must have no leading zeroes, unless the string is "0"
.
Example 1:
Input: 2
Output: "110"
Explantion: (-2) ^ 2 + (-2) ^ 1 = 2
Example 2:
Input: 3
Output: "111"
Explantion: (-2) ^ 2 + (-2) ^ 1 + (-2) ^ 0 = 3
Example 3:
Input: 4
Output: "100"
Explantion: (-2) ^ 2 = 4
Note:
0 <= N <= 10^9
