One problem for all exercises

[Darya1113]

When I try to run fazzer I have one error for all exercises.

[-] Hmm, looks like the target binary terminated before we could complete a
handshake with the injected code. You can try the following:

- The target binary crashes because necessary runtime conditions it needs
  are not met. Try to:
  1. Run again with AFL_DEBUG=1 set and check the output of the target
     binary for clues.
  2. Run again with AFL_DEBUG=1 and 'ulimit -c unlimited' and analyze the
     generated core dump.

- Possibly the target requires a huge coverage map and has CTORS.
  Retry with setting AFL_MAP_SIZE=10000000.

Otherwise there is a horrible bug in the fuzzer.
Poke the Awesome Fuzzing Discord for troubleshooting tips.

[-] PROGRAM ABORT : Fork server handshake failed
Location : afl_fsrv_start(), src/afl-forkserver.c:1642

Can you help me?
Thanks
