In last Codeforces Round 1072 (Div. 3), in problem C : https://codeforces.me/contest/2184/problem/C
My submission in constest time : https://codeforces.me/contest/2184/submission/357537571
After system test, my submission : https://codeforces.me/contest/2184/submission/357713730
2 submitted code are same, but first one got hacked.
how is it possible?
Bro, the second submission, there are no test that is the same as the hack test. Your second submission is still wrong but no hacks so ... ACCEPETED!!!
but as far as i know, system test include all the test case and hacking attempt test case also..
idk, I think they forgot to put the hacks to the main tests
it appears they haven't added successful hacks to systests yet. cc Vladosiya
