Materials
• There are no additional materials required for this paper. For Examiner’s Use
• You must not use a calculator.
Question Mark
Instructions 1
• Use black ink or black ball-point pen. Use pencil only for drawing.
2–3
• Answer all questions.
• You must answer the questions in the spaces provided. 4–5
• If you need extra space for your answer(s), use the lined pages at the end of this 6–7
book. Write the question number against your answer(s).
8–9
• Do all rough work in this book. Cross through any work you do not want to be
marked. 10–11
• Questions that require a coded solution must be answered in Python. 12
• You should assume that all indexing in code starts at 0 unless stated otherwise.

0 1 Figure 1 shows an algorithm, represented using pseudo-code.
The algorithm assigns different values to two variables, then asks the user to input a
letter.
Figure 1
film "Godzilla vs. Kong"
year 2021
OUTPUT "Please guess a letter"
letter USERINPUT
0 1 . 1 Which pseudo-code statement assigns the length of the string filmto a variable called value?
Shade one lozenge.
[1 mark]
A film LEN(value)
B film film + value
C value film
D value LEN(film)
0 1 . 2 The POSITIONsubroutine returns the position of the first occurrence of a character in a
string.
For example:
• POSITION("Godzilla vs. Kong", "o")would return 1
• POSITION("Godzilla vs. Kong", "z")would return 3 letterand filmare
variables used in the algorithm in Figure 1.
Complete the pseudo-code statement to find the position of the first occurrence of the
contents of letterin filmand store this position in the variable location
You must use the POSITIONsubroutine in your answer.
