// Functions! We've already seen a lot of one called "main()". Now let's try
// writing one of our own:
//
// fn foo(n: u8) u8 {
// return n + 1;
// }
//
// The foo() function above takes a number "n" and returns a number that is
// larger by one.
//
// If your function doesn't take any parameters and doesn't return anything,
// it would be defined like main():
//
// fn foo() void { }

const std = @import("std");
pub fn main() void {
// The new function deepThought() should return the number 42. See below.
const answer: u8 = deepThought();

// We're just missing a couple things. One thing we're NOT missing is the
// keyword "pub", which is not needed here. Can you guess why?
