Problem B. The Great Hero
***** There was an issue in problem Div2B: in author solution there was long long overflow, which, sadly, wasn't noticed by author and coordinator, and handling this overflow wasn't intended as part of the problem. On all tests the C++ main solution had the same answer as Python solution - either the overflow didn't occur or it accidentally gave the same answer YES/NO. During the contest, some hacks failing main solution were created, if they were added, majority of solutions would fail. |
