One step at a time

if runs a group of instructions when its condition is true. else runs the other group when it is false. end closes the decision.

The round is ready when there are at least 2 players. Change the starting player count and see which message is chosen.

Your task

Set players to 1 so the program displays Waiting. Keep the decision to explore how a false condition chooses else.

Expected output

Waiting

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

See another example

local players = 3
if players >= 2 then
    print("Ready")
else
    print("Waiting")
end

Run the starter to see the current behavior, then make the change in the task.
