THE PROBLEM

🌲 Invert a binary tree! 🌲

Except with 3 catches:

1. It must invert the keys ("bit-reversal permutation")
2. It must be a dependency-free, pure recursive function
3. It must have type Bit -> Tree -> Tree (i.e., a direct recursion with max 1 bit state)

// Extremely hacky server program that will send a standard response
// to every client that connects, then closes the connection. Will
// issue no system calls (as measured by `strace`) after initial setup
// no matter how many requests are served.

// Yes, this program is sorely lacking in error checking. It's a toy
// and not meant to be taken seriously.

// compile with gcc no_syscall_server.c -luring
