Demo Program

function factorial (num: i32) -> i32{
  let result = 1;
  
  for i in 2 to num {
      result = result * i;
  }
  
  return result;
}

function cube (num : i32) -> i32 {
    return num * num * num;
}

function demo_match(num: i32) -> i32 {
   let result = 1;

   # syntactic sugar for if else
   match once {
     result < 30 => {result = 30;}
     result < 50 => {result = 45;}
   }

  return result;
}
