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 6–7
the end of this book. Write the question number against your
8–9
answer(s).
Do all rough work in this book. Cross through any work you do 10–11
not want to be marked. 12
Questions that require a coded solution must be answered in Python.
13–14
You should assume that all indexing in code starts at 0 unless stated otherwise.

0 11 shows an algorithm, represented using pseudo-code.
Figure
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 film to 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 POSITION subroutine 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 letter and film are 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 letter in film and store this position in
the variable location
You must use the POSITION subroutine in your answer.
