CodeChefRating 1843Open on judge ↗

Chef has $3$ hidden numbers $A, B,$ and $C$ such that $0 \leq A, B, C \leq N$. Let $f$ be a function such that $f(i) = (A \oplus i) + (B \oplus i) + (C \oplus i)$. Here $\oplus$ denotes the [bitwise XOR](https://en.wikipedia.org/wiki/Bitwise_operation#XOR) operation. Given the values of $f(0), f(1), \dots, f(N)$, determine the values of $A, B,$ and $C$. It is guaranteed that **at least** one tu
