Two extra lines are being added to the end of the algorithm in Figure 1.

Fill in the gaps so the output from the new final line will be the string 'Manchesterdiff' (all lowercase for 'diff').

Assume that:

• Array indexing starts at 0.
• String indexing starts at 0.
• SUBSTRING(start_index, length, value) returns a substring of length length starting at position start_index from the string value.

temp ← SUBSTRING( _____ , _____ , city2)

OUTPUT cities[ _____ ] + temp

Figure 1

1  cities ← ['Bristol', 'Manchester', 'London']
2  city1 ← 'Edinburgh'
3  city2 ← 'Cardiff'
4  OUTPUT city1
5  OUTPUT LEN(cities)
6  temp ← SUBSTRING(4, 5, city1)
7  OUTPUT temp
