1. The pseudocode algorithm below is intended to calculate the average birth weight of all
babies born in a hospital over a period of time, and the maximum and minimum birth weight
recorded. It does not give the correct results.
1 total = 0
2 maximum = 0
3 minimum = 100
4 numB = 0
5 weight = 0
6 while weight != -1
7 weight = float(input("Please enter weight"))
8 if weight != -1
9 total = total + weight
10 if weight > maximum
11 weight = maximum
12 endif
13 if weight < minimum
14 weight = minimum
15 endif
16 numB = numB + 1
17 endif
18 endwhile
19 average = total / numB
20 print(numB)
21 print(average)
22 print(maximum)
23 print(minimum)
(a) Give five line numbers which show the program structure sequence. [1]
(b) Give the line numbers on which iteration starts and ends. [2]
(c) Give the line numbers on which selection starts and ends. [2]
