I'm noticing a concerning pattern among interviewees where I work; smart c++ coders who know about O notation and SIMD, but have no idea that memory management is a thing / important for performance.
A lot of them solve performing math on >64bit numbers by storing the numbers in strings too 😶
@logicalerror May I ask what's the preferred way? An array of long long?
@alvis an array of 8, 16, 32 or 64 bit integers that you use to basically simulate an integer of x bits that can be enlarged when necessary

@logicalerror Great, thank you! Now I think I'm smarter than those smart c++ coders😎
@alvis well, their failure is mostly a lack of knowledge I think
(but you might very well be smarter!)
