## Solution
When we connected to the service we reached a command line service which reverse the input we provide. Since the challenge name reminds us about format string we attempted to leak informations:```%x %d %x```
No particular output is provided... Let's try to puts it in reverse order:```x% d% x%```
Boom, format string exploit confirmed! We sprayed some `%{i}$s` to leak all the string pointed by stack values and we got the flag.
