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 'Manchesterdon'.

Figure 1

1  cities ← ['Bristol', 'Manchester']
2  city1 ← 'London'
3  city2 ← 'Cardiff'
4  OUTPUT city1
5  OUTPUT LEN(cities)
6  temp ← SUBSTRING(0, 3, city1)
7  OUTPUT temp

temp ← SUBSTRING( _____, _____, city1)
OUTPUT cities[ _____ ] + temp
