Can someone have a look at my code please? I'm getting 62 test cases right, then a WA

thanks
Does anyone know why I am getting std:bad_alloc on a few cases? My code works in my IDE without any errors. Any help would be very appreciated.

The cause of

-bit integers can take up to 
MB of storage. In addition, 
MB of storage in the worst case.
std::bad_alloc
is unrelated to where the vector is located (in general, only fixed sized arrays have issues when allocated locally). The issue is that your code is exceeding the memory limit for this problem. A two dimensional vector of sizevector::push_back
can result in the actual capacity of the vector being up to twice as large as the actual size (assumingvector::reserve
is not called), thus resulting inYou should aim for a solution that uses
memory.
