Here are some submissions of F 279625545 279590206 279609951 279581737
All of them have some ANTIHACK macros or something like that. Obviously they can't anti-hack, they just make their codes hackable. But the problem comes: many submissions have slightly difference to others so they can't be easily hacked just by one code. Almost every hackable code needs special designs, which is quite annoying :(
And I also found some lol submissions: 279596731 279629539. They have the cheating codes in the submission, but the submission is surprisingly unhackable lol
Just by checking the codes after sorting by execution time, I found that more than 4 in 5 submissions are hackable, omg...
antihack is crazy
I always wonder how you people find these things? I once tried and spend hours for absolutely nothing
LOL I take it some trolling was going on in those cheater groups
There are a lot of cheaters who don't use their brains to think about what problem they are trying to solve.
D. Satyam and Counting (I think they didn't try to read the problem.)
