In the above problem when I’m using pragmas:
#pragma GCC optimize(“Ofast”)
#pragma GCC target(“avx,avx2,fma”)
My code is giving runtime error SIGILL,but without it code got accepted.
I just want to know why is it happening?Is there any problem in using pragmas because I have been using pragmas in my code for a while but never encountered such error ever.
plaese anyone clear my doubt>
