## 题目

Given a positive integer, output its complement number. The complement strategy is to flip the bits of its binary representation.

Example 1:

1 | Input: 5 |

Example 2:

1 | Input: 1 |

**Note:**

- The given integer is guaranteed to fit within the range of a 32-bit signed integer.
- You could assume no leading zero bit in the integer’s binary representation.
- This question is the same as 1009.

## 思路

Easy题，按题目要求操作即可，没什么好说的打个卡而已。。。
