Minimize Xor Difference

You are given $2$ integers $A$ and $B$. Find *any* integer $X$ ($0 \leq X \lt 2^{30}$) such that $| (A \oplus X) - (B \oplus X) |$ is **minimized**. Here, $\oplus$ denotes the [bitwise XOR](https://en.wikipedia.org/wiki/Bitwise_operation#XOR) operation, and $|A|$ denotes the [absolute value](https://en.wikipedia.org/wiki/Absolute_value) of $A$. If there are multiple possible $X$ that minimize t
