Order by XOR

You are given three **distinct** integers $A, B,$ and $C$. Find **any** integer $X \ (0 \leq X < 2^{30})$ such that: $(A \oplus X) \lt (B \oplus X) \lt (C \oplus X)$, where $\oplus$ denotes the [Bitwise XOR operation](https://en.wikipedia.org/wiki/Bitwise_operation#XOR). If no such $X$ exists, print $-1$ instead. ### Input - The first line of the input contains a single integer $T$, the numb
