Loops inspect each item

Many levels use a loop: start with a simple value, visit each item, update the answer, then return it at the end.

💡 Hint ladder

Count DOWN with: for i = n, 1, -1 do ... end
Build the text as you go: result = result .. i .. "... "
Add "GO!" after the loop.

💬 A for loop can count DOWN with a -1 step. Watch it build a string.

  end
  return result
end

print(stars(3))  -- ***
print(stars(6))  -- ******
