the difference in timings could be because of the println!() macro maybe? what if you try the same but you do not print at line 3 and 10?

That was a great suggestion, thank you - yes, makes a big difference! -

So println! is best used only at the end, makes sense now!

@@learning_rust cool! I'm fairly new to Rust my self, such an enjoyable language

@@ALL-THE-SUN Yeah, can be difficult, but I like a lot - the more I learn the more I like it- I need a faster laptop to do projects on though, as compiling can take a while...
