An algorithm for an automated supermarket checkout kiosk helper is shown in Figure 1.

Regardless of what the user inputs, the same number of OUTPUT instructions will always execute when the algorithm runs.

Figure 1

1  OUTPUT 'Welcome to the automated checkout.'
2  bagOption ← USERINPUT
3  IF bagOption = 'yes' THEN
4      OUTPUT 'How many bags do you need?'
5      count ← USERINPUT
6      IF count > 5 THEN
7          OUTPUT 'Please ask an assistant for assistance.'
8      ELSE
9          OUTPUT 'Please scan your items now.'
10     ENDIF
11 ELSE
12     OUTPUT 'Do you have your own bags?'
13     ownBag ← USERINPUT
14     IF ownBag = 'yes' THEN
15         OUTPUT 'Please scan your items now.'
16     ELSE
17         OUTPUT 'A helper will bring a basket.'
