Task 12 Modulo and time difference wrong check

If we try the input 4 18 42 32 15 2 24 45

the expect answer that the computer gave me was: (10 7 42 13)

When I calculate, I find this answer may be wrong, but it must be (10 7 12 13) . Can you check this for me.

Hi, I find out the answer, thank you
