Question
What will be the output of Pseudocode?Integer n, rev, rem, origSet n = 61206, rev = 0Set orig = nWhile n NOT EQUALS 0 rem = n MOD 10 rev = rev * 10 + rem n = n / 10End whileIf (orig IS EQUAL TO rev) Print revElse Print (orig – rev) / 6End If
Solution
The pseudocode provided is a program to reverse a number and then check if the original number is equal to the reversed number. If they are equal, it prints the reversed number. If they are not equal, it subtracts the reversed number from the original number, divides the result by 6, and prints the result.
Let's go through the pseudocode step by step:
- Initialize
nto 61206,revto 0, andorigton(61206). - Enter a while loop that continues as long as
nis not equal to 0. - Inside the loop,
remis set to the remainder ofndivided by 10. This effectively gets the last digit ofn. revis then updated to berevtimes 10 plusrem. This effectively adds the last digit ofntorev, shifting any existing digits inrevone place to the left.nis then divided by 10, effectively removing the last digit.- Repeat steps 3-5 until
nis 0. - After the loop, check if
origis equal torev. If they are equal, printrev. - If
origis not equal torev, subtractrevfromorig, divide the result by 6, and print the result.
Now, let's run the pseudocode with the given value of n (61206):
nis 61206,revis 0, andorigis 61206.- Enter the while loop.
remis 6,revis 6, andnis 6120.remis 0,revis 60, andnis 612.remis 2,revis 602, andnis 61.remis 1,revis 6021, andnis 6.remis 6,revis 60216, andnis 0.- Exit the while loop because
nis 0. orig(61206) is not equal torev(60216), so subtractrevfromorig(990), divide by 6 (165), and print the result.
So, the output of the pseudocode will be 165.
