Why some hacked solutions on yesterday's div3 can still get the Accept now ? Shouldn't those hack test cases be added for all? Otherwise, it is unfair like why the one hacked only to suffer wrong ans or time limit verdict and his rank go down?
Yesterday's B : Hacked 208823417 That was my 1st solution to the problem. It fails in case n = 1e9 and k = 30 because of taking MOD when doing the binary exponentiation (It was a typo taking the MOD just copying my template but it still wrong)
Another Hacked B 208731078 for K = 63 , it overflows 1LL << K as max for long long is 2^63-1 so adding 1 would overflow
However, why they still pass ? And shouldn't those test cases be added for all contestants ?
UPD : Resolved
