One step at a time

A for loop runs its block once for each number from the start to the end. Here round is 1, then 2, then 3.

Your task

Change the final limit so this loop displays the numbers 1, 2, 3, and 4.

Expected output

Lines must stay in order. Spelling, capitalization and spaces inside a message matter.

See another example

for step = 1, 2 do
    print(step)
end

The loop prints 1 and then 2, once for each value of step.

Syntax in this activity

New syntax: for round = 1, 3 do, end
