Hi.Thanks for pointing that out.Pls note You must have missed out the entire working deliberately and just seen that one mistake. I think that shows what kind of educator you are.There's no need to be a jerk about it. You must be very free to downvote stuff, kindly find something more constructive to do.

Hey Pal, The entire working is flawless except for that last statement. Maybe you want to take a good look first ?

In fact, before you delete the answer uploaded, u can check on who down vote your answer. The app might have some error instead of down vote, it shown up vote. By checking number of votes, it can tell who down vote you....

The App is not available on my side as the app is only available for older android versions.So the internet access is the only way to log on. Yeah,it's not necessary that it's you who downvoted but since I can't check it on the site it made you seem like the one . No worries pal.I had to reupload as it wouldnt let me place the solution picture.Maybe the person who downvoted ,would like to say something ?
