What will be the output of the following pseudo-code ?

Integer a
Set a = 5
do
   print a - 2
              a = a- 1
while (a not equals 0)
end while

A

5 3 0

B

3 0

C

infinite loop

D

None of these

Explanation

Let's break it down quickly:

Initial value: a = 5.
In each loop iteration:
- Prints a - 2.
- Decreases a by 1.
The loop stops when a becomes 0.

Iterations:

First: prints 5 - 2 = 3, a becomes 4.
Second: prints 4 - 2 = 2, a becomes 3.
Third: prints 3 - 2 = 1, a becomes 2.
Fourth: prints 2 - 2 = 0, a becomes 1.
Fifth: prints 1 - 2 = -1, a becomes 0.

The loop stops when a = 0.

Output:

3 2 1 0 -1

So the correct answer is:
(D) None of these

Correct Answer: B) 3 0
