Hello there,
Just wanted to ask if there's a real difference between e.g.
the "long" type and "int_fast64_t" in terms of execution times.
Thanks
```int_fast64_t``` is the fastest 64-bit or larger integer type.
The type that is at least 64 bits long and works fastest on the
platform is selected. This type can be selected if performance is
more important than memory and the processor can run faster on
certain types.
```long``` is an integer that is strictly 64 bits long. That is,
this type is permanently 64 bits and provides cross-platform
portability. If you want strictly 64 bits and care about
cross-platform consistency, you should use this type.
So you have to choose between consistency and efficiency. When
you tell the compiler this choice, it implements it if it can
agree with the processor.
