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 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
