Hi Jinsuk,
Thank you for the support. I am a beginner myself but I will try to
understand the code. My problem is if you look at (code.png) it is the code
that is providing me the error. The code2 is the output that I am
getting(erroneous). And code 3 is the output I should be getting. Somehow,
the program is skipping even values after 0.
It would be a huge help to a beginner like me if you can glance at it and
point me in the right direction.
Thanks
