Problem Statement

Quite often one needs loops which, in the last iteration, execute only part of the loop body. Demonstrate the best way to do this. Write a loop which writes the comma-separated list using separate output statements for the number and the comma from within the body of the loop.

Let's start with the solution:

fn main() {
    for i := 1; ; i++ {
        print(i)
        if i == 10 {
            break
        }
        print(", ")
    }
}
