plz can u explain why u wrote it like that?
like how it came to u to think about it

People often upvote the solution they understand or the one similar to what they did, so it's more of the most popular solution rather than most clever or fastest

the data type is integer so 1.5 will change to 1 automatically

could you please explain whats going on after the 0ull

you should only use & in a for loop if you intend to modify the element

Not really. In general you should always access the element by reference (i.e. " &x" if you need to modify it, or "const &x" if you don't), otherwise C++ must make a copy into the loop varible. HOWEVER, in the case of a built-in type like int, just getting a copy is (almost?) always just as efficient or more efficent that getting the elements address and then deref'ing it.

xd wow
