## Reflected Binary Conversion

Given a number, implement the conversion from binary to reflected binary.

Reflected binary is an alternate binary representation where numbers in sequence only change a single bit at a time. For example, the numbers 0 through 4 are represented in binary and reflected binary below. This is also known as Gray code.

| Number | Binary | Reflected |
|--------|--------|-----------|
| 0      | 0000   | 0000      |
| 1      | 0001   | 0001      |
| 2      | 0010   | 0011      |
| 3      | 0011   | 0010      |
| 4      | 0100   | 0110      |

```c
uint toReflected(uint x) {
  return x ^ (x >> 1);
}
```
