The complement of an integer is the integer you get when you flip all the 0's to 1's and all the 1's to 0's in its binary representation.
- For example, The integer
5is"101"in binary and its complement is"010"which is the integer2. Given an integern, return its complement.
Example 1:
Input: n = 5
Output: 2
Explanation: 5 is "101" in binary, with complement "010" in binary, which is 2 in base-10.
Example 2:
Input: n = 7
Output: 0
Explanation: 7 is "111" in binary, with complement "000" in binary, which is 0 in base-10.
Example 3:
Input: n = 10
Output: 5
Explanation: 10 is "1010" in binary, with complement "0101" in binary, which is 5 in base-10.
Constraints:
0 <= n < 10^9
