# flag di compilazione -pthread lib per il threading -O0 disabilita ottimizzazione
# optimization levels:
# O0 -> no optimization, faster compilation time
# O1 -> basic optimization, reduces code size and improves performance, no significant change in compilation time [removes dead code, simple inlining, basic loop transformations]
# O2 -> advanced optimization, balances performance improvements with code size [O1 optimizations + loop unrolling, vectorization, better instruction scheduling]
# O3 -> maximum optimization, increased compile time and binary size [O2 optimizations + aggressive inlining, aggressive loop optimizations, function cloning]
# Ofast -> [O3 optimizations + aggressive math optimizations]
