Question
Find the output of the following pseudo-code:
Integer value, n
Set value = 1, n = 45
while(value less than equal to n)
value = value *4
value/=2
end loop
Print value
radio_button_unchecked 64
radio_button_unchecked 32
radio_button_unchecked 44
radio_button_unchecked 45
Solution
The pseudo-code starts with two variables, value and n, which are set to 1 and 45 respectively.
Then, it enters a while loop that continues as long as value is less than or equal to n.
Inside the loop, the value is multiplied by 4 in each iteration.
After the loop, the value is divided by 2.
The loop will run as follows:
- In the first iteration, value is 1, which is less than 45, so it multiplies value by 4, resulting in value being 4.
- In the second iteration, value is 4, which is still less than 45, so it multiplies value by 4 again, resulting in value being 16.
- In the third iteration, value is 16, which is still less than 45, so it multiplies value by 4 again, resulting in value being 64.
At this point, value is no longer less than or equal to n (45), so the loop ends.
After the loop, the value is divided by 2, resulting in value being 32.
So, the output of the pseudo-code will be 32.
Therefore, the correct answer is:
radio_button_unchecked 64
radio_button_checked 32
radio_button_unchecked 44
radio_button_unchecked 45
