Scrambled Message
==================
## Text
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 three files, `scrambled_message.rkt` contains a bit of code to
get you started, `message.bin` contains the captured message the spy
has been transmitting, and `memory.bin` contains the memory dump.
We think that the memory dump contains the positions of the characters
of the classified information in the message, find out if this is the
case and recover the leaked information.
## Files
* `message.bin`
* `memory.bin`
* `scrambled_message.rkt`
## How To Solve
See `scrambled_message_solution.rkt`.
Solution is not there!
