that really kills me, i wanted to write some codes to calculate the problem, but after some thoughts, i gave up,cuz even the codes could solve it, it has to calculate billions of times, there must be some other unregular method.

all i got is

32 18 19 29
21 27 26 24
25 23 22 28
20 30 31 17

but obviously, it doesnt completely meet the requiements.
Gimme some more time
