Question 2

An algorithm is shown in the pseudocode below.

1  minerals ← ['Quartz', 'Gypsum', 'Feldspar']
2  min1 ← 'Calcite'
3  min2 ← 'Fluorite'
4  OUTPUT min1
5  OUTPUT LEN(minerals)
6  result ← SUBSTRING(2, 5, min2)
7  OUTPUT result

SUBSTRING returns a portion of a string containing the characters from the start index to the end index inclusive (using 0-based indexing). For example, SUBSTRING(1, 3, 'Python') will return the string 'yth'.

State the output of line 7 from this algorithm.
