Answer all questions. box 0 1 Figure 1 shows an algorithm, represented using pseudo-code, which assigns a different value to four variables. Figure 1 country  'United States of America' state  'California' city  'San Francisco' landmark  'Alcatraz Island' 0 1 . 1 Define the term algorithm. [2 marks] 0 1 . 2 The variable x is assigned a value using the statement: x  LEN(state) Using Figure 1, what is the value of x? Shade one lozenge.

For example, SUBSTRING(3, 5, 'Computing') would return put The variable y is assigned a value using the statement: y  SUBSTRING(4, 7, landmark) Using Figure 1, what is the value of y? Shade one lozenge. [1 mark] A Alca B Atra C land D traz Question 1 continues on the next page 4 *04* IB/G/Jun23/8525/1C Do not write outside the Figure 1 box has been included again below.

For example, POSITION('Computing', 'p') would return 3 The variable z is assigned a value using the statement: z  POSITION(landmark, 't') Using Figure 1, what value is assigned to z?
