Q1.
What value of COUNT will be output after the instructions corresponding to the following pseudocode are executed, assuming 7 values - 5, 6, 7, 3, 0, 4, 2 - are input, one on each record?
COUNT = 0
SUM = 0
VALUE = 1
DOWHILE VALUE > 0
Read VALUE
Write Value
SUM = SUM + VALUE
COUNT = COUNT + 1
ENDDO
Write SUM, COUNT

b)5
c)6
d)7
Q2.
What statement(s) are unnecessary in the following pseudocode?
