for number in 1..<10 excludes 10. However, doing 1<..10 to exclude 1 does not work. How does one do that?

if the FOR - IN loop implicitly uses a constant, could it be used in anyway to modify the value of each element?

I'm just confused why we use a constant in For In Loops? We are changing the output- isn't that a variable?
