What will be the output of the following pseudocode?

Integer i

Set i = 3

do

print i + 3

i = i - 1

while(i not equals 0)

end while

What would be the output of the following pseudocode?

Integer a

String str1

Set str1 = “goose”

a = stringLength(str1)

Print (a ^ 1)

Note: ^ is XOR operator

What will be the output of the following pseudocode?

Integer a, b

Set a = 15, b = 7

a = a mod (a - 3)

b = b mod (b – 3)

What will be the output of the following pseudocode?

Integer a, b, c

Set b = 5, a = 2, c = 2

if(b>a && a>c && c>b)

b = a + 1

Else

a = b + 1

End if

2. It produces all pair shortest path tree

Choose the correct answer from the options given below.

• Both 1 and 2 are true

• Both 1 and 2 are false

• Only 2 is true
