Mini-mission

Use a familiar idea in a different task. Read the changed requirement before running.

Your task

With count = 0, display Empty. == checks whether values are equal. Check count == 0 before the general count <= 3 branch that displays Low.

Expected output

Empty

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

See another example

local level = 12
if level >= 10 then
    print("Mentor")
elseif level >= 5 then
    print("Workshop")
else
    print("Training")
end

Only Mentor appears because the first matching branch handles this value.

New syntax: elseif

if checks the first condition. elseif checks another condition only when earlier ones were false. else handles the remaining cases. end closes the decision.

Order matters when several conditions could be true. Check the most specific case first. A high-level visitor also meets a lower requirement, so a general check placed first can hide a special message.

Each return finishes this function call. Different branches may return different messages, but each visitor receives one result.
