A spy has been transmitting classified information from our agency to the enemy,
we need to find out what information was transmitted. Unfortunately, the spy
has scrambled his communications. Luckily, we could dump the memory of
his 32 bit little endian based computer.
You get two files, `scrambled_message.rkt` contains a bit of code to
get you started, and `memory.bin` contains the memory dump.
We think that the memory dump consists of a header followed by
the actual data that was transmitted by the spy.
The header should consist of the message length, followed by
the positions of interesting characters.
Good luck!
